Does the following infinite series converge or diverge? explain your answer. 7+28+112+448+

To determine whether the series converges or diverges, we will need to get the value of r.
If r is greater than 1, then the series converges
If r is less than 1, then the series diverges

In the given series:
r = 28/7 = 112/28 = 448/112 = 4

Based on the above, this series converges
