The given series is in the below pattern,
First term = 36
Second term = First term × 6
⇒ Second term = 36 × 6 = 216
Third term = Second term × 0.3
⇒ Third term = 216 × 0.3 = 64.8
Fourth term = Third term × 6
⇒ Fourth term = 64.8 × 6 = 388.8
Fifth term = Fourth term × 0.3
⇒ Fifth term = 388.8 × 0.3 = A
∴ A = 116.64
So, 116.64 will come in place of A.
Similarly , we can find all others terms also.
now , 116.64 ÷ 36 = 3.24
