In this video I discuss how to calculate the n'th term of nonlinear sequences, by introducing the idea of first and second differences.

(6) The difference here will either be a constant number, in which case the n th term is (1/2a)n 2 +d. Or like this case, will itself follow a linear sequence with constant difference, which we …
