A sequence is defined by f(0)=3, f(n)=2*f(n-1)for n>1.Write a definition for the nth term of f.

Answer 1

Mark, with all due respect (to someone who almost always hits the nail on the head), I think the question is looking for the solution to the difference equation with initial condition f(0)=3.

f(n) = 3 * 2ⁿ for n>0.

Answer 2

In the video I explain the given recursive form of the sequence, and show how to find the explicit form of the sequence.
