Question

4,6,18,90,486,3645,32805
find the wrong term

Answer 1

90 is the wrong term.It should be 81.
Second term(6) is the product of first term and 1.5
Third term is the product of second term and twice of 1.5 (2*1.5)
So the fourth term should be the product of 3rd term and (3*1.5 that is 81

All other terms also follow this format if 81 is in place of 90
