Question

66,36,18.... solve this

Answer 1

Answer:

12

Step-by-step explanation:

66,36,18,—

Let us write the series in reverse direction and let the missing term is X

x,18,36,66…

dividing all terms by 6

x/6,3,6,11

Here 6–3=3

and 11–6=5

Thus difference is increasing by 2

thus 3-x/6=1

x/6=2

x=12

Thus the missing term=12

so the final series becomes

12,18,36,66

Answer 2
