Answer» Given: Third term of a G.P, T3 = 4 ∴ ar2 = 4 …(i) To find: Product of first five terms So, First five terms are a, ar, ar2, ar3 and ar4 ∴ Product of first five terms = a × ar × ar2 × ar3 × ar4 = a5r1+2+3+4 = a5r10 = (ar2)5 = (4)5 [from (i)] Ans. The third term of a G.P. is 4, the product of the first five terms is (4)5. |
