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

The answer is -5.

Step-by-step 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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
