All ai ⋲ N, so yes they are. And for n = 2 I eventually receive that √(a1 * a2) ≤ 1/2 (a1 + a2)
Or a1 * a2 ≤ [(a1 + a2)^2] / 4. Not entirely sure why I would want to do multiple base cases, but I think you are on the right track.
Homework Statement
Show via induction that the nth root of (a1 * a2 * a3 * ... an) ≤ 1/ (n) * ∑ ai, where i ranges from 1 to n.
