So x/25.088= 2.5

x= 2.5x25.088= 62.72

Answer 2

Answer:

The missing number is 62.72

Step-by-step explanation:

Consider the provided series.

980, 392, 156.8, ?, 25.088, 10.0352

In order to find the missing number you need to determine the pattern.

Observe the pattern as shown:

$\frac{392}{980}=0.4$

$\frac{156.8}{392}=0.4$

$\frac{?}{156.8}=0.4$

$?=62.72$

Now we can check whether the number is correct or not.

$\frac{25.088}{62.72}=0.4$

Hence, the missing number is 62.72
