Question

What will be the 25th term of the following series: 3,4,6,12......

Answer 1

It not an A.P.

Because common difference is not constant.

Answer 2

Answer:

-3/5

Step-by-step explanation:

first we will do reciprocal of the no.s

1/3,1/4,1/6,1/12

it becomes an AP now

now common difference= 1/4 - 1/3 = -1/12

now 25th term = a +(n-1)d

1/3 + 24× -1/12 = -3/5
