Show that the progression -27, 9, -3, 1,(-1/3) , ...... is a G.P. Write its (i) first term (ii) common ratio (iii) nth term (iv) 9th term.

Question

KnowledgeBoat · Accepted Answer

Given, -27, 9, -3, 1, ,...... . Since, ratio between consecutive terms are equal, thus the series is in G.P. a = -27 r = We know that, nth term of a G.P. is given by, Tn = arn - 1 9th term Hence, a = -27, r = , Tn = = , T9 = .
