Ineed to know how to get the answer to get that number i need

The number is - 19.

Step-by-step explanation:

Note that the distance between - 10 and - 4 = | -10 - (-4)| = | -6|

= 6 units

That means the distance between -4 and the line to its immediate left is 3 units.

So, proceeding this way, - 4 - 3 = - 7

- 7 - 3 = - 10

- 10 - 3 = - 13

- 13 - 3 = - 16

- 16 - 3 = - 19 which is third to the left of - 10.

Hence, the number should be - 19.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
