Question

Look at the following number sequence 9 15 21 27 Based on the pattern, what are the next two terms?

Answer 1

thirty three
thirty nine
you add six

Answer 2

33 and 39.

Explanation:

We have been given a sequence 9, 15, 21, 27. We are asked to find next two terms of our given sequence.

First of all, we will find common difference by two consecutive terms of our given sequence.

`15-9=6`

`21-15=6`

`27-21=6`

We can see that each term of our given sequence is 6 more than previous term.

To find next term of our sequence, we will add 6 to 27 as:

`27+6=33`

To find next term of our sequence, we will add 6 to 33 as:

`33+6=39`

Therefore, the next two terms of our given sequence are 33 and 39.
