# What will be the next term of this series? 4, 9, ?, 34, 54

Question:

## What will be the next term of this series? 4, 9, ?, 34, 54

Options:

`A. 21`
`B. 19`
`C. 23`
`D. 25`

Solution:

The series is an arithmetic progression, which means that each term is equal to the previous term plus a constant value. In this case, the constant value is 5, 10, 15…. . So, to find the next term, we simply add 5, 10, 15…. to the last term, which is 54.

Here is the complete series:

``4, 9, 19, 34, 54``

4 + 5 = 9

9 + 10 = 19

19 + 15 = 34

34 + 20 = 54
