Topic: Geometric Progression Insert 5 terms between 576 and 9, so that they form GP.
Asked by Pankaj | 26 Sep, 2018, 06:47: AM
answered-by-expert Expert Answer
Let a = 9 and ar6 = 576
Let 5 terms between them are ar, ar2 ar3 ar4 ar5 
ar6 = 576
9r6 = 576
r6 = 64
r = ±2
Taking r = 2 we get 
ar = 18, ar2 = 36, ar3 = 72, ar4 = 144, ar5 = 288
% terms between 9 and 576 are 18, 36, 72, 144, 288 for r = 2
Considering r = -2 find the terms.
