Please help, its very urgent. A sequence can be generated by using an=13an−1, where n is a whole number greater than or equal to 1.

Given a11=6, what is a12?

Ithink the answer is d i hope it

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
