Find the next three terms of the sequence 3, 9, 27, 81, . .
a. 81, 243, 729
b. –243, –729, –2187
c. 87, 249, 87
d. 243, 729, 2187

The pattern is x3.
3x3=9
9x3=27
27x3=81
81x3=243
243x3=729
729x3=2187

D is your answer.

Yes she would be correct the answer is three or your equation for your sequence  Is t(n)=1*3(to the power of x)^x

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.
