Find the sum to infinity of a decreasing GP with the common ratio x such that |x| < 1; x ≠ 0. The ratio of the fourth term to the second

Question 1

Find the sum to infinity of a decreasing GP with the common ratio x such that |x| < 1; x ≠ 0. The ratio of the fourth term to the second term is 1/16 and the ratio of third term to the square of the second term is 1/9.

Question 2

Let the series be a, ax, ax2, ax3, … given that |x| < 1 and x ≠ 0. Also,

But, since it is a decreasing GP ⇒ x = 1/4
