Question

What are the next terms in the sequences below 19 , 15 , 11 , 7 , 3 , -1 , _

Answer 1

The answer is -5.

Explanation:

As you look at the first 3 terms, all have the common difference of 4. So the next term after -1 is :

19 - 4 = 15

15 - 4 = 11

11 - 4 = 7

7 - 4 = 3

3 - 4 = - 1

- 1 - 4 = - 5
