Third term=4
Step-by-step explanation:
Given:
C(n)=4/9(-3)^n-1
Find the third term
Let n=3
Substitute n=3 into the equation
C(n)=4/9(-3)^n-1
C(3)=4/9(-3)^3-1
Step 1: evaluate the power 3-1
C(3) = 4/9(-3)^2
Step 2: evaluate (-3)^2
C(3) = 4/9(9)
It can be rewritten as
C(3) = 4/9*9
9 numerator will strike 9 denominator out leaving 4
C(3)=4
Therefore, the third term=4
C(3)=4
