Proof step 13 from proof bertrand-holds-lower (previous step)

prime(5), prime(7), prime(13), prime(23), prime(43), prime(83), prime(163), prime(317), prime(631), prime(1259), i ≤ 1024, 0 < i, i < 82 ⊦ ∃ j. prime(j) ∧ i < j ∧ j ≤ 2 * i

User applied rule exists right

And obtained the following new goals

Proof step 14:
prime(5), prime(7), prime(13), prime(23), prime(43), prime(83), prime(163), prime(317), prime(631), prime(1259), i ≤ 1024, 0 < i, i < 82 ⊦ prime(83) ∧ i < 83 ∧ 83 ≤ 2 * i, ∃ j. prime(j) ∧ i < j ∧ j ≤ 2 * i
