Q:

What should come in place of question mark (?) in the following number series?

38, 195, ?, 4905, 24530, 122655

A) 980	B) 885
C) 824	D) 1021

Answer & Explanation Answer: A) 980

Explanation:

The given series follows the pattern that,

×5+5, ×5+5, ×5+5, ×5+5, ×5+5

38 x 5 + 5 = 195

195 x 5 + 5 = 980

980 x 5 + 5 = 4905

4905 x 5 + 5 = 24530

24530 x 5 + 5 = 122655

So the missing number is 980 .
