Answer: |x+2|={x+2;x≥−2−(x+2)
Step-by-step explanation:
: The absolute value function |x+2| can be defined as the piecewise function.
The nth term is (presuming the denominator on the first is a typo)

The ratio of successive terms is

The limit is -1/3, absolute value less than 1, so the series converges. It has a sum -- that's what converges means.
