To solve this problem, you can use a trick that holds true for every possible triplet of consecutive integers: their sum is always three times the middle number.

In fact, if you call the middle number x, the three consecutive numbers are x-1,\ x,\ x+1 and their sum is (x-1)+x+(x+1) = x+x+x-1+1 = 3x

So, since \frac{267}{3} = 89, the middle number is 89. So, the three numbers are 88, 89, 90.

Write an equivalent series with the index of summation beginning at n = 1. ∞ (−1)n + 1(n + 1)xn n = 0
kkurt [141]

Looks like the starting series is

\displaystyle\sum_{n=0}^\infty\left((-1)^n+1\right)(n+1)x^n

Note the degree of the first few terms in the series, for n=0,1,2, are x^0,x^1,x^2, and so on.

So if the series were to start at n=1, we would need to preserve that pattern, and we do that by replacing n with n-1:

\displaystyle\sum_{n=1}^\infty\left((-1)^{n-1}+1\right)(n-1+1)x^{n-1}

Simplifying a bit, we end up with

\displaystyle\sum_{n=1}^\infty\left(1-(-1)^n\right)nx^{n-1}
