Find the missing number and letters in the following series C 81 E 64 ? 49 I ? K

(a) G, 36

(b) F, 36

(c) G, 32

(d) H, 24

**Answer: (a) G, 36 **

**Explanation:-**

C + 2 = E & (9 – 1)^2 = (8)^2 => 64,

Same as,

E + 2 = G and (7 – 1)^2 = (6)^2 => 36.

Then, the missing number and letters in the series are G, 36.

Hence, the correct answer is option (a) G, 36.
