Expand the general term: [k(k+1) = k^2 + k] Substitute back into the sum: [S = \sum_{k=1}^{n} (k^2 + k) = \sum_{k=1}^{n} k^2 + \sum_{k=1}^{n} k] Use the known formulas for the sums of ( k ) and ( k^2 ): [\sum_{k=1}^{n} k = \frac{n...
In math typesetting, the term axis refers to a horizontal reference line used for positioning elements in a formula. The math axis is similar to but distinct from the baseline for regular text layout. For example, in a simple equation, a minus symbol or fraction rule would be on the axis...

Since our series starts at x=0, and the x=0 term is 0, we have: \sum_{x=0}^{\infty} x r^x = \frac{r}{(1-r)^2} Plugging in r = \frac{1}{2}: \sum_{x=0}^{\infty} x\left(\frac{1}{2}\right)^x = \frac{\frac{1}{2}}{(1 – \frac{1}{2})^2} = \frac...
