Question

Show that the progression 0.4, 0.8, 1.6,..... is a G.P. Write its (i) first term (ii) common ratio (iii) nth term (iv) 7th term.

KnowledgeBoat · Accepted Answer

Given, 0.4, 0.8, 1.6,..... Since, ratio between consecutive terms are equal, thus the series is in G.P. a = 0.4 r = = 2 We know that, nth term of a G.P. is given by, Tn = arn - 1 7th term, T7 = = . Hence, a = 0.4, r = 2, Tn = , T7 = .
