Answer: 1,89,-9

Step-by-step explanation:

13th term of the geometric sequence is 732,421,875

Give that;

Geometric sequence 3, -15, 75,

Find:

13th term of the geometric sequence

Computation:

First term a = 3

Common ratio r = a2 / a1 = -15 / 3 = -5

Number of term n = 13

An = arⁿ⁻¹

A13 = (3)(-5)¹³⁻¹

A13 = (3)(-5)¹²

A13 = (3)(244,140,625)

A13 = 732,421,875

13th term of the geometric sequence = 732,421,875
