Question

66,36,18,? whats the next term?

Answer 1

66,36,18 then the next term is 12
Explaination:-
Let us reverse the series (just for a better understanding, since we are comfortable with growing up :p). It now becomes X 18 36 66.

Divide by 2 the complete series. It becomes X/2  9 18 33.

The difference between consecutive terms is _,9,15. The _ can only be filled by 3 to make the difference logical (3,9,15).

3 => series = 6 9 18 33

=> actual series = 12 18 36 66

Divide by 3 => X/3  6 12 22

The difference between consecutive terms is _,6,10. The _ can only be filled by 2 to make the difference logical (2,6,10).

2 => series = 4 6 12 22

=> actual series => 12 18 36 66

Divide by 6 => X/6   3 6 11.

The difference between the consecutive terms is _,3,5. The _ can only be filled by 1 to make the difference logical (1,3,5).

1 => series = 2 3 6 11

=> actual series = 12 18 3 66.

So, by all means, the answer is 12
