I have tried and tried, with no success. Instructor is useless, book is far more useless, there's nothing worse than online math class. Can anyone help me answer this problem? I am trying to do my homework, I've done one number right.

I need to answer 11 more, this is the 2nd of them.

This is discrete math, Induction.

This is the question:

Alumberjack has 4n + 110 logs in a pile consisting of n layers.

Each layer has two more logs than the layer directly above

it. If the top layer has six logs, how many layers are there?

And i attached an image of an example that is somewhat similar to what I am supposed to do.
