In a geometric sequence, as = 8 and a7 = 32.
Use the geometric mean to find the value of a6

a6=16

Step-by-step explanation:

a5=8

a7=32

Let q be the ratio: a6=a5×q

a7=a6×q=a6×(a6/a5)

a7×a5=a6²

a6=sqrt(a7×a5)=sqrt(32×8)=sqrt(256)=16

a=16

i think it might be a but you might want a second opinion

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.
