find the next three numbers in this pattern: 1,1.25, 1.5, 1.75,...

Question

This is Pre algebra. i just can't figure it out.

Answer 1

Ask yourself this question.  Does the pattern have a common difference or a common ratio?

 

If common difference, then add the last term to the common difference.

If common ratio, then multiply the last term by the common ratio.

 

As you can see, the common difference is 0.25.  Use that fact to find the next three numbers.
