38 19 28.5 71.25 18 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (d)?

Correct Answer: 118.125

Explanation:

The given series is in the below pattern ,
First series :-
First term = 38
Second term = First term × 0.5
Second term = 38 × 0.5 = 19
Third term = Second term × 1.5
Third term = 19 × 1.5 = 28.5
similarly , we can find the all others terms .
Second series :-
First term = 18
Second term = First term × 0.5
Second term = 18 × 0.5 = 9
Third term = Second term × 1.5
Third term = 9 × 1.5 = 13.5
Fourth term = Third term × 2.5
Fourth term = 13.5 × 2.5 = 33.75
Fifth term = Fourth term × 3.5
Fifth term = 33.75 × 3.5 = 118.125
So 118.125 should come in place of (d).
