Our institutional research engineers are currently mapping the formal proof for Cauchy Sequences.

Analytical Intuition.
Cauchy is clustering convergence. Terms get arbitrarily close to each other. We don't need to know the limit, only that points are huddling together. Ultimate tool for proving convergence.
CAUTION
Institutional Warning.
In the reals, Cauchy and Convergent are identical. The criterion looks at internal behavior.
Academic Inquiries.
01
Is every bounded sequence Cauchy?
No, oscillating sequences like (-1)^n are bounded but don't huddle.
