Question

4.
Does the following infinite series converge or diverge? Explain your answer.
7 + 28 + 112 + 448 +...
It converges; it does not have a sum.
6
It diverges; it has a sum.
It diverges; it does not have a sum.
It converges; it has a sum.

Answer 1

Answer:

It diverges; it does not have a sum.

Step-by-step explanation:

7 + 28 + 112 + 448 +...

Since the numbers keep getting larger and the ratio is greater than 1, the series will diverge

r = 28/7 = 4

Answer 2

Diverges and doesn't have sum
