Answer 2

The missing term in the series 23, 25, 71, 361, ?, 22681 is 2519

Given,

The number series is 23, 25, 71, 361, ?, 22681

To find,

The missing term in the series

Solution,

The given number series  is 23, 25, 71, 361, ?, 22681

In order to find the missing term, firstly we must find the relation between the terms available.

The relation can be found using any arithmetic operations like addition, subtraction, multiplication, division, etc.

So, the relation between the terms is:

Term 2 = Term 1 * 1st odd number + 1st even number

Term 3 = Term 2 * 2nd odd number - 2nd even number

Term 4 = Term 3 * 3rd odd number + 3rd even number

Term 5 = Term 4 * 4th odd number - 4th even number

we get.,

25 = 23 * 1 + 2

71 = 25 * 3 - 4

361 = 71 * 5 + 6

2519 = 361 * 7 - 8

22681 = 2519 * 9 + 10

Hence,

The missing term in the series 23, 25, 71, 361, ?, 22681 is 2519
