Question

Find the 15th term of the following sequence.

5, 8, 11, 14 ....

Answer 1

Make a pattern first for the numbers present:
5+3n, where n is the nth term and the first term is n=0

The 15th term = 5+3(15) = 50

You can check it by doing it the long way as well (writing down all the numbers)

Answer 2

thank you very much
