Determine if the sequence is arithmetic or geometric, write the explicit equation and then find the given term. 1. 11th term: 5, 3, 1,-1, ...
2. 23rd term: 0.1,0.15, 0.2, 0.25, ...
3. 6th term: 25, 75, 225, 675, ...
4. 22nd term:-2, -5, -8, -11, -14,
5. 10th term: a = 320, r = 0.5
6. 50th term: -9.2, 13. 24. 35.

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.
