Question 1204298
What is the 10th term of the geometric sequence -3, 15, -75...?



the geometric sequence -3, 15, -75...?

15/-3 =-5

-75/15=-5common ratioo = -5

nth term of GP = {{{Tn = ar^(n-1)}}}

a=-3, r=-5

t10 = -3*(-5)^(10-1)


t10 = -3*(-5)^(9)

=5859375

10th term of the geometric sequence -3, 15, -75... is 5,859,375.
