Question

List the first three terms of this sequence: an = 3 • 5n – 1

Answer 1

1st term = 14

2nd term = 29

3rd term = 44

Explanation:

1st term = 3 x (5x 1) - 1

= 3 x 5 - 1

= 15 - 1 = 14

2nd term = 3 x ( 5 x 2 ) - 1

= 3 x 10 - 1

=30 - 1 = 29

3rd term = 3 x (5 x 3 ) - 1

= 3 x 15 - 1

= 45 - 1 = 44
