Look at this series: 

8, 22, 8, 28, 8, ... 

What number should come next?

The correct answer is
34

Understanding the Number Series Pattern

The given number series is 8, 22, 8, 28, 8, ... We need to find the next number in this sequence.

Let's analyze the series step-by-step:

  • The series alternates between the number 8 and another number.
  • The number 8 appears in the 1st, 3rd, and 5th positions. It seems to be a constant element in the odd-numbered positions.
  • Now let's look at the numbers in the even-numbered positions: 22 (2nd position) and 28 (4th position).
  • We observe a difference between these two numbers: $28 - 22 = 6$.

Identifying the Next Term

Based on the observed pattern:

  • The number in the 1st position is 8.
  • The number in the 2nd position is 22.
  • The number in the 3rd position is 8.
  • The number in the 4th position is 28, which is $22 + 6$.
  • The number in the 5th position is 8.
  • Following the pattern, the number in the 6th position should be the previous even-positioned number (28) plus 6.

Calculation:

Next term = Number at 4th position + 6

Next term = $28 + 6$

Next term = $34$

Conclusion

The pattern consists of the number 8 followed by a number that increases by 6 each time (22, 28, 34, ...). Therefore, the number that should come next in the series is 34.

Important Questions from Number Series

  1. In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of :: ?
    (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
