WebSep 7, 2015 · Clearly this is an arithmetic sequence with common difference d = 2 between terms. The general term for this sequence may be given as : xn = a + (n − 1)d , where a = first term, n = number of terms. Hence, xn = 1 + (n −1)(2) = 2n −1. Writing xn = 99 and solving for n gives that 99 is the 50th term. Now to add all the terms of this ... WebWhat is the Sum of all Numbers from 1 to 99?
