Question

On a number line there are six spaces. On the first is the number 2, on the last space is the number 42, on the third space is x, solve for x.
Thanks!

Answer 1

1st space is 2
6th space (last) is 42
in betwen that is 5 spaces to go
find distance from 2 to 42
42-2=40

40=5 spaces
divide 5
8=1 space
each space goes upby 8

2=1st space
2+8=2nd space
2+8+8=3rd space=18=x


x=18
