I just started studying mathematical induction, and I'm having a bit of trouble.
The question is simply: The first three terms of an arithmetic sequence are $u_1 = 1, u_2 = 3, u_3 = 5$. Prove that $u_n = 2n - 1$ using mathematical induction.
The questions I've tackled so far only concerned series (like, the sum of n terms in a series). This one got me scratching my head a bit.
Thank you so much!
