WebOne method is to get an in terms of n. Since the first term is 16, and each term after the first is 3 more than the previous term, it follows that the nth term is an = 16 + 3 (n - 1). So we have the quadratic equation 252 = n [16 + 16 + 3 (n - 1)]/2, which we can then solve for n. WebOne way to represent this is by multiplying the terms by (-1)^i or (-1)^ (i+1) (where i is the summation index). To represent your example in summation notation, we can use i* (-1)^ (i+1) where the summation index is in the range [1, 10].
