Answer:
Step-by-step explanation:
Since you are only going out 4 terms, you could just list the terms and add.
5*(-2/3)^0 = 5 * 1 = 5
5*(-2/3)^1 = 5 *(-2/3) = -10/3
5*( - 2/3)^2 = 5*(-2/3)^2 = 5*(4/9) = 20/9
5*(-2/3)^3 = 5*(-2/3)^3= 5 *(-8/27) = -40/27
Answer
5 - 10/3 + 20/9 - 40/27
5 - 90/27 + 60/27 - 40/27
5 - 70/27
2 11/27
