Does This Sequence Converge?
/in Algebra, Calculus, College Algebra, L'Hopital's rule, limits, Math Test Prep, sequences, series/by Jill HackerQuestion Does the sequence converge? Solution A sequence converges if there is a limit for its terms as the number terms goes to infinity. Is there a limit of as goes to infinity? Let’s see: . Since the limit as goes to infinity of equals 0, the limit as goes to infinity of . There […]
Solving Radical Equations
