WebClearly, the first term is 1 1, the last term is 100 100, and the number of terms being added is also 100 100. Substitute the values into the formula then simplify to get the sum. Since {a_1} = 1 a1 = 1, {a_ {100}} = 100 a100 = 100, and n = 100 n = 100 we have Thus, the sum of the first 100 100 natural or counting numbers is 5,050 5,050. WebYou may have subtracted 1 instead of adding 1 in the last step. The nth term of an arithmetic series is given by a_n = a + d (n - 1), where a is the first term and d is the common difference. We know that a = -50, d = 6, and a_n = 2,044. So 2,044 = -50 + 6 (n - 1); 2,094 = 6 (n - 1); 349 = n - 1; n = 350.
