(d) H, 24​

the missing number is 36 and letter is G

Answer 2

Answer:

The missing number and letters are G and 36.

Step-by-step explanation:

Given the number and letter series C 81 E 64 ? 49 I ? K.

In letter series, letters are given leaving the immediate next one.

             C, E, ?, I, K.

After E, leaving F, it must be G.

In number series, squares of the numbers are given.

Starting from 9 decreasing by one.

             $81, 64, 49, ?\implies 9^{2} , 8^{2},7^{2} ,?$

So, the next number must be $6^{2} =36$  

Therefore the missing number and letters are G and 36.
