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.
