Question 973866: Write the nth term of the geometric sequence as a function of n. ,
The underscore denotes a value in subscript, and thank you!! Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! a_1 = -3-1 = -4
a_n = (-4) * (-4)^(n-1) = (-4)^n
note that the common ratio is -4
the sequence looks like
-4, 16, -64, 256, .....
