If the first term, common ratio and the last term of a G.P. are a, r and l respectively, then the nth term from the end of the G.P. is given by : 1. lrn - 1 2. lr1 - n 3. 4.

Question

KnowledgeBoat · Accepted Answer

When the G.P. is reversed, the first term becomes l and the new common ratio is the reciprocal of the original common ratio i.e. . Hence, option 2 is the correct option.
