Question

Find the fourth term of infinite geometric sequence if the sum of the second and the third term is equal to 3 and the sum of the geometric sequence is equal to 8.

The Common Ratio is a rational number.


`|q| \ \textless \ 1 \ \textless \ =\ \textgreater \ \lim q^n = 0\\=\ \textgreater \ S = (a_(1))/(1 - r)\\S = 8\\a_2 + a_3 = 3\\a_4 = ?`
