Elham, Nicole, and Kaymon are making paper from a combination of wood pulp, and cotton using a constant ratio. Elham uses 5g. of wood pulp and 2g. of cotton. If Kaymon uses 20g of wood pulp, How much cotton should he use?

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
