What is the value of the 11th term in the following geometric sequence?

-5, - 10, - 20, - 40

-5,120

-100

-180

-19,531,250

The geometric sequence above is - 5*2^ (x-1)

plugging in 11 we get - 5*2^10

which is - 5120

we are given the geometric sequence - 5, - 10, - 20, - 40. The geometric factor of this sequence is equal to 2. In this case, the formula is expressed: an = - 5 * (2) ^ (n-1) where n is an integer. In this case, a11 is equal to - 5 * (2) ^ (11-1) equal to - 5120.
