Answer 2

Answer:

5.12

Step-by-step explanation:

Given:- 1250, 500, 200, 80, 32, 12.8

To Find:- The next number in the series.

Solution:- The given series is 1250, 500, 200, 80, 32, 12.8, ?

To find the next number we need to find the pattern in the given number series.

Now, as we can see 1250 × $\frac{4}{10}$ = 125 × 4 = 500 i.e. the second term.

Third term is  500 × $\frac{4}{10}$ = 50 × 4 = 200,

Fourth term is 200 × $\frac{4}{10}$ = 20 × 4 = 80,

Fifth term is 80 × $\frac{4}{10}$ = 32,

Sixth term is 32 × $\frac{4}{10}$ = 12.8,

Seventh term is 12.8 × $\frac{4}{10}$ = 5.12.

Therefore, the series is 1250, 500, 200, 80, 32, 12.8, 5.12.
