Just had a request, can we have some exam style questions on Arithmetic and geometric sequences based on sigma notation? In the exam, some of the sigma notation questions are extremely confusing, many of them have 3 terms in their nth term and it confuses the hell out of me

Hi sir, I've looked through all your videos but can't seem to find one on geometric sequences when you are not given the first term.

e.g. uₙ₊₁ = (√2 - 1)uₙ + 4
Find the limit of the sequence as n → ထ

These type of questions seem more complicated.
