Proof step 5 from proof pot-01 (previous step)

2 ^ ((n - 1) + 1) = 2 * 2 ^ (n - 1) ⊦ 2 * 2 ^ (n - 1) = 2 ^ n, n = 0

Heuristic elimination applied rule insert elim lemma

And closed the goal!

Rule argument

spec: nat name: elim-pred-c seq: n ≠ 0 ⊦ m = n - 1 ↔ n = m + 1 subst: [n, m] → [n, m]

Additional information

Used simplifier rules: n ≠ 0 ⊦ m = n - 1 ↔ n = m + 1; (elim) Used terms: n, m
