Question

If x 2x+2 3x+3 are in gp then the fourth term is

Answer 1

In question

First term(a)=x

Common difference= 2x+2÷x

Answer 2

Answer:

As we know

second term/first term=r

therefore

r=2x+2/x

so fourth term=third term x r

=(3x+3)(2x+2)/x

=6x^2+6x+6x+6/x

=6x^2+12x+6/x

=x(6x+12+6/x)/x

fourth term =6x+12+(6/x)
