(i) Also, t 6 = ar 5 ∴ ar 5 = 1 81 ∴ r r 1 3 r 2 × r 5 = 1 81 ... [From (i)] ∴ r 3 = 1 27 ∴ r = 1 3 Concept: Geometric Progression (G. P.)
WebAug 17, 2024 · a = 16 Explanation: Equation of nth term in GP: Tn = (a*r)^(n-1) t2 = 24 that means a*r = 24 t5 = 81 that means a*(r)^4 = 81 t5/t2 => 81/24 That means (r)^3 = 81/24 Therefore r = 3/2 Substituting value of r in t2 we get, a*(3/2) = 24 Therefore a = 24*(2/3) Hence a = 16 Find Math textbook solutions?
