How to find an explicit formula from a recursive sequence
I would to show you a general strategy for figuring out an explicit formula when we are given a sequence defined recursively. Solving linear recurrence relations is usually taught in discrete math but we are seeing an introduction in precalculus. This method of finding an explicit formula from a recursive sequence should be what you should try first!

5:20 "both" a_n=2a_(n-1)+3
