Patterns in Mathematics — solved examples for Class 6 CBSE

Example 1easy

Look at the number pattern: 3, 7, 11, 15, ... Which rule correctly describes how to get the next number in this sequence?
  1. A)Add 3 to the previous number
  2. B)Multiply the previous number by 2
  3. C)Add 4 to the previous number
  4. D)Subtract 4 from the previous number

Step-by-step solution

  1. Let's find the difference between consecutive numbers:
  2. 7 - 3 = 4
  3. 11 - 7 = 4
  4. 15 - 11 = 4
  5. Since the difference is consistently 4, the rule is to add 4 to the previous number.

Answer: Add 4 to the previous number

Example 2medium

Observe the pattern: 2, 7, 12, 17, 22, ... If this pattern continues, what will be the 8th term in the sequence?
  1. A)37
  2. B)32
  3. C)27
  4. D)42

Step-by-step solution

  1. First, identify the pattern by finding the difference between consecutive terms: 7 - 2 = 5, 12 - 7 = 5, 17 - 12 = 5, 22 - 17 = 5.
  2. The pattern is to add 5 to the previous term to get the next term. This is an arithmetic progression.
  3. The given terms are the 1st (2), 2nd (7), 3rd (12), 4th (17), 5th (22) terms.
  4. To find the 8th term: 6th term = 22 + 5 = 27; 7th term = 27 + 5 = 32; 8th term = 32 + 5 = 37.

Answer: 37

Example 3hard

Observe the pattern of dots: Figure 1 has 1 dot. Figure 2 has 3 dots. Figure 3 has 6 dots. Figure 4 has 10 dots. If this pattern continues, how many dots will Figure 8 have?
  1. A)28
  2. B)36
  3. C)45
  4. D)55

Step-by-step solution

  1. The pattern of dots is 1, 3, 6, 10, ... This is a sequence of triangular numbers.
  2. The rule for the nth triangular number (T_n) is T_n = n × (n + 1) / 2.
  3. For Figure 8 (n=8), the number of dots will be T_8 = 8 × (8 + 1) / 2 = 8 × 9 / 2 = 72 / 2 = 36.

    2. B)162
    3. C)192
    4. D)216
    Show answer

    Answer: 162

    Hint: Check if the numbers are increasing by a constant amount or by a constant multiple.

  2. Q2.easy

    A pattern is made using squares. The first figure has 1 square. The second figure has 4 squares arranged in a 2x2 grid. The third figure has 9 squares arranged in a 3x3 grid. How many squares will the fourth figure have?
    1. A)12
    2. B)16
    3. C)20
    4. D)25
    Show answer

    Answer: 16

    Hint: Notice how the side length of the square grid changes with each figure number.

  3. Q3.easy

    Which of the following statements about odd and even numbers is always true?
    1. A)The sum of two odd numbers is always an odd number.
    2. B)The product of an odd number and an even number is always an odd number.
    3. C)The product of two odd numbers is always an odd number.
    4. D)The sum of two even numbers is always an odd number.
    Show answer

    Answer: The product of two odd numbers is always an odd number.

    Hint: Try testing each statement with a few examples of odd (1, 3, 5) and even (2, 4, 6) numbers.

  4. Q4.medium

    A clock shows the time 3:00. After 30 minutes, the minute hand moves 180°. If a pattern of rotations is 90° clockwise, 180° clockwise, 270° clockwise, what will be the next rotation in this sequence?
    1. A)90° clockwise
    2. B)360° clockwise
    3. C)180° clockwise
    4. D)450° clockwise
    Show answer

    Answer: 360° clockwise

    Hint: Look at the amount added to each rotation to get the next one. What's the step-by-step increase?

  5. Q5.medium

    Consider the sequence of numbers: 1, 3, 6, 10, 15, ... What will be the 8th term in this sequence?
    1. A)21
    2. B)28
    3. C)36
    4. D)45
    Show answer

    Answer: 36

    Hint: Instead of a constant difference, look at how the difference between consecutive terms changes. Is there a pattern in those differences?

  6. Q6.medium

    Rohan goes to school every Monday, Wednesday, and Friday. If he started this schedule on a Monday, on which day of the week will his 10th school day fall?
    1. A)Tuesday
    2. B)Wednesday
    3. C)Thursday
    4. D)Friday

    Answer: Friday

    Hint: List out the days he goes to school. How does the sequence of days repeat? Count carefully.

  7. Q7.hard

    Consider a pattern where squares are arranged to form a larger square with a hollow center. Figure 1 is a 3x3 square with a 1x1 hollow center (8 squares). Figure 2 is a 4x4 square with a 2x2 hollow center (12 squares). Figure 3 is a 5x5 square with a 3x3 hollow center (16 squares). How many squares will be in Figure 6?
    1. A)20
    2. B)24
    3. C)28
    4. D)32
    Show answer

    Answer: 32

    Hint: Focus on how the dimensions of the outer square and the hollow center change with each figure number. The number of squares is the area of the outer square minus the area of the inner hollow.

  8. Q8.hard

    A special machine processes numbers. When you input '1', it outputs '3'. When you input '2', it outputs '8'. When you input '3', it outputs '15'. When you input '4', it outputs '24'. If the machine outputted '99', what number was inputted?
    1. A)7
    2. B)8
    3. C)9
    4. D)10
    Show answer

    Answer: 9

    Hint: Look for a pattern in the relationship between the input number (n) and the output number. How does the output relate to n and n+1 or n+2?

  9. Q9.hard

    A unique plant grows in a special way. On Day 1, it has 2 leaves. Each subsequent day, the plant grows twice the number of *new* leaves it grew on the previous day. Additionally, it grows 1 new flower every day starting from Day 1. How many total leaves and flowers will the plant have on Day 5?
    1. A)34 leaves, 5 flowers
    2. B)30 leaves, 5 flowers
    3. C)30 leaves, 10 flowers
    4. D)34 leaves, 10 flowers
    Show answer

    Answer: 34 leaves, 5 flowers

    Hint: Track the number of *new* leaves added each day and the cumulative total. The flowers have a simpler, independent pattern.
