Write the following series using sigma notation.
$4+8+12+16+20+\text{. . .}$4+8+12+16+20+. . .
Consider the series $-3+9-27+81-243+729$−3+9−27+81−243+729.
Consider the series:
$\frac{1}{1^3}+\frac{1}{2^3}+\frac{1}{3^3}+\frac{1}{4^3}+\frac{1}{5^3}$113+123+133+143+153
Rewrite the series using sigma notation in the form $\sum_{k=\editable{}}^{\editable{}}\editable{}$∑k=.
