The formula for the nth term of a geometric sequence is given by:
an = a1 * r^(n-1)
Using the values given:
a1 = 128
r = -1/2
n = 5
We can plug these values into the formula to find the term indicated:
a5 = a1 * r^(5-1)
a5 = 128 * (-1/2)^(4)
a5 = 128 * 1/16
a5 = 8
Therefore, the fifth term of the geometric sequence is 8.
find the term indicated in each of the following geometric sequence a1=128,r=-1/2,n=5
