Answer 1

Answer: The second term of the sequence is 2

Explanation:

Given the function c(n) = -6(-1/3)^n-1

To get the second term of the sequence, we will substitute n =2 into the given function to have;

c(2) = -6(-1/3)^2-1

c(2) = -6(-1/3)^2-1

c(2) = -6(-1/3)^1

C(2) = -6(-1/3)

Since -×- a= +

C(2) = +6/3

C(2) = 2

Therefore the second term of the sequence is 2
