Question

If the n terms of two A.P.s are in the ratio (3n+4): (n+4) the ratio of the fourth term

Answer 1

First n terms are in the ratio (3n+4): (n+4)

to find Ratio of 4th terms, put n=4

Ratio of 4th terms = (3×4+4) : (4+4)

= (12+4) : (8)

= 16 : 8

= 2:1

Ratio of 4th terms is 2:1

Answer 2

the ratio is put the value 4 at the place of n bcz n can be any integer so the ratio is same for all so just put n=4
we get 2:1
