MHB Prove that the sequence converges to 0 (2)

[alexmahone]

e_{n+1} = (e_n-2)/(e_n+4)

Prove that {e_n} converges to 0 if

(a) e_0 > -1

(b) -2 < e_0 < -1

PS: I haven't learned things like sup and inf yet, so please don't use them.

Look at the other question you posted. The idea is very similar.
Also it would help if you post your work so we can help you with your steps.
