When copy-pasting problems from other sources (the "enter INF if it diverges..." is a dead giveaway here), it's important to pay attention to formatting. It's not clear exactly what the terms of this series should be.
However, there's certainly a Geometric Series involved, and it probably diverges due to the 8^n terms.
