WebThe following is the formula for calculating the general term, nth term, or last term of the geometric progression: an= nth term. a1=first term. r=common ratio. n=term position. To get the total value of the supplied terms of a geometrical series, apply the formula for the sum of the geometric progression or series. WebSolution Verified by Toppr Correct option is B) Let the first term of G.P be 'a' and common ratio be 'r' given T p+q=ar p+q−1=m T p−q=ar p−q−1=n then multiplying the above two equations : mn=a 2r 2p−2=(ar p−1) 2 ⇒ar p−1= mn but ar p−1 is the p th term of the G.P hence T p= mn Was this answer helpful? 0 0 Similar questions
