101 + 102 + 103 + .... + 200 S = (100 + 1) + (100 + 2) + (100 + 3) + ...+ (100 + 100) Thus, it consists of 100 terms. = (100 + 100 + 100 + .... 100 times) + (1 + 2 + 3 + ...... + 100) = (100 × 100) + (1 + 2 + 3 + ..... + 100) = (10000) + (1+ 2 + 3 + ... + 100) = 10000 + 5050 = 15050 Here, a = 101, d= 102–101 = 1 l = 200 an= a + (n – 1)d 200 = 101 + (n – 1)1 n – 1 = 99
