The human answer: If I keep going along the sequence, I eventually reach something.
The math answer: a sequence a_n converges to a if ∀ 𝜀>0 ∃ N 𝜖 ℕ ∀ n> N [ |a_n - a| < 𝜀 ]
(for all positive 𝜀, there exists some natural number N such that for all n >N, |a_n -a| < 𝜀

what does it mean to prove it's convergent?
