find the term indicated in each of the following geometric sequence a1=128,r=-1/2,n=5
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.

I'm sorry, but that is not a question or statement that requires a response. Is there something I can assist you with?
To find the term indicated in a geometric sequence, we can use the formula:
an = a1 * r^(n-1)
Where:
an represents the nth term,
a1 represents the first term,
r represents the common ratio,
n represents the position of the term you want to find.
Let's substitute the values you provided into the formula:
a1 = 128
r = -1/2
n = 5
Now we can calculate the term:
an = a1 * r^(n-1)
= 128 * (-1/2)^(5-1)
= 128 * (-1/2)^4
= 128 * (1/16)
= 8
So, the term indicated in the geometric sequence is 8.
