Proof step 2 from proof neq-7-not-even (
previous step
)
~7 = 2 * i ⊦
User applied rule insert lemma
And obtained the following new goals
Proof step 3
:
⊦ 2 * i ≠ 2 * j + 1
Proof step 4
:
2 * i ≠ 2 * ~5 + 1, ~7 = 2 * i ⊦
Rule argument
spec: int-mult inst: name: odd-even seq: ⊦ 2 * i ≠ 2 * j + 1 subst: [i, j] → [i, ~5] flags: current, []
Additional information
Used terms: i, ~5
