Find an equation for the nth term of the arithmetic sequence.
8, 6, 4, 2, (2 points)

an = 8 + -2(n)

an = 8 - 2

an = 8 + -2(n + 1)

an = 8 + -2(n - 1)

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
