Answer 1

Answer:

-10

Step-by-step explanation:

So it skipped labeling a marker as a number between 10 and 2. The difference between 10 and 2 is 10-2=8.

Half of 8 is 4. So it is going down by 4 each time.

So start at the marker called 10.

The next marker would be 10-4=6.

The next labeled marked is 2 which would do get 2 from doing 6-4=2.

The next one below 2 would be 2-4=-2.

The next one below that one would be -2-4=-6.

The ? would be -6-4=-10.
