Question

 whrite down the next two numbers in the sequence 7.5, 8.75, 10, 11, 25, _, _

Answer 1

Did you by any chance mean to write "11.25" instead of "11,25"? If so, the sequence is arithmetic. You can prove this by subtracting each term from the one after it:

8.75-7.5 = 1.25

10 - 8.75 = 1.25

11.25 - 10 = 1.25 (this is why I asked if you had a typo).

So all you have to do is add 1.25 each time you want another term.
