Which equation could you use to find 15 ÷ 3? 15 + 3 = 18 18 – 3 = 15 3 × 5 = 15 30 ÷ 2 = 15

The sixth term of the sequence is:

                    +80 or -80

The 5th term of geometric sequence is given by:

We know that the nth term of a geometric sequence with first term a and common difference r is given by:

Also, we have:

and

on dividing 7th term by 5th term we get:

Hence, the sixth term of the sequence is given by:

         Hence, the sixth term of the geometric sequence is:

                +80 or -80
