WebMay 8, 2024 · 12K 1M views 4 years ago nth term How to find a formula for the nth term in a linear sequence, and how to find other terms in a sequence; here we find the 100th … WebTo do this we start by letting a n + 1 − a n = Δ a n and we call this operation on a n the forward difference. Then given Δ a n we can find a n. Sum both sides of the equation from n = 0 to x − 1, and note that we have a telescoping series: ∑ n = 0 x − 1 Δ a n = ∑ n = 0 x − 1 ( a n + 1 − a n) = a x − a 0 Hence a n = a 0 + ∑ i = 0 n − 1 Δ a i.
