Question

ANTHE Q-30 : 124:64::123:27::126:216::122:? Which number replaces ? Mark

Answer 1

8 is the answer.
Explanation↓↓
in first part,
it's 124 then it is 4 cube 64
then, in second part,
it's 123 which is 1 less than 124, so then it's 27, cube of 3 which is one less than 4,
similarly, in third part,
it's 126 which is 3 more than 123, then it's 216, cube of 6 which is also 3 more than 3.

At last, in fourth part,
it's 122 which is 4 less than 126,
so then take second one as 8, cube of 2, which is 4 less than 6
