Explanation:-
-1 + 1 = 0,  0 + 1 + 2
= 0 + 3 = 3,
3 + 3 + 2 = 3 + 5
= 8,
8 + 5 + 2 = 8 + 7
= 15,
Similarly, 15 + 7 + 2
= 15 + 9
= 24

Then, the missing number is 24.

Hence, the correct answer is option (d) 24.

Explanation:-
6 + 3 = 9  &  2 + 2 = 4,
4 + 2 = 6  &  9 = 3 = 12.

Then, the missing numbers are 6, 15.

Hence, the correct answer option (c) 6, 15.

Explanation:-
The opposite place values of A C E = Z X V,
And E + 2 = G,
The opposite place values of G I K = T R P,

Same as, K + 2 =  M.
Then, the missing number is M.

Hence, the correct answer is option (a) M.
