Answer 2

Given,

The number series 57, 72, 98, 21, 34, X, 123​

To Find,

The value of X in the given number series.

Solution,

To solve the given number series, we first need to find out the relation between the numbers given.

If we look at the first two numbers in the series,

⇒ 57 + 72 = 129

In, the next pair of numbers.

⇒ 98 + 21 = 119

It shows that the addition of the pair of numbers is decreasing by 10.

∴ The next two pairs of numbers will be,

⇒ 34 + X = 109

⇒ X = 109 - 34

⇒ X = 75

Hence, the value of X in the given number series is 75.
