Hi there, I'm currently working through the maths which i have to do next year. I've done around 2/3 of it but the problem with being on holiday is that i have nobody really to ask when i have a problem with a study related question. RE2: Q67: A sequence of numbers is given by the relation: U_(n) = 3.(2/3)^n - 1 Where n is a positive integer. Prove that 3u_(n+1) = 2u_(n) - 1. I'm not at all sure where to go with this. It's a proof question so i can't exactly just work out the values for each value of n and put them in the equation. Thanks.
