calculate the least no of terms of gp 5+10+20+...whose sum would exceed1000000 Share with your friends Share 4 Vipin Verma answered this Sum of GP = a(rn-1)(r-1)Here a = 5, r = 2 So 5(2n-1)(2-1) ≥ 1000000 (2n-1) ≥ 200000 So 2n ≥ 200001 So for n ≥ 18 equation (1) is satisfying, so least number of term is 18. -1 View Full Answer
