Question

determine 4th term in the geometric sequence whose first term is -2 and whose common ratio is -5. does anyone know what this can possibly be?

Answer 1

The terms in a geometric sequence are given by: A = ar^(n-1)
where A is the nth term in the sequence.
a = first term in the sequence (-2)
r = common ratio (-5)
n = number of the term (4)

A = (-2)(-5)^(4-1)
A = (-2)(-5)^(3)
A = (-2)(-125)
A = 250
