Question
The number that comes next in the number sequence is
8, 10, 13, 17, 22, ___
- 23
- 24
- 26
- 28
Hint:
We are given a number series with last term missing. We are asked to find the last term. We have to find the rule used to write the series. Using the rule, we will find the required value.
The correct answer is: 28
The given sequence is 8, 10, 13, 17, 22
We will find the rule used to write the sequence.
We will subtract the previous term from its next term.
10 – 8 = 2
13 – 10 = 3
17 – 14 = 4
22 – 17 = 5
If we see, the difference between the terms increasing by 1. So, for the next term the difference will be 5 + 1 = 6
The last term is 22.
We will add 6 to the last term to get the next term.
22 + 6 = 28
Therefore, the missing term of the series is 28.
For such questions, we should know the basic operations. When the rule used to write the pattern is not mentioned, we have to use all four operations to check the pattern. The operations are addition, subtraction, division, and multiplication.
