I have the following sets of numbers (3 lines):

1.8, 1.82, 1.85, 1.88, 1.92, 1.96, 2.01, 2.07, 2.14, 2.24, 2.34, 2.48, 2.66, 2.91, 3.29, 3.89, 5.01, 7.75

2.25, 2.28, 2.31, 2.34, 2.38, 2.43, 2.48, 2.55, 2.62, 2.74, 2.85, 3, 3.21, 3.5, 3.94, 4.64, 5.94, 9.13

2.79, 2.82, 2.85, 2.88, 2.92, 2.97, 3.03, 3.09, 3.17, 3.3, 3.42, 3.59, 3.82, 4.15, 4.64, 5.43, 6.92, 10.58

They all increase in value, I am sure there must be some equation to work out further numbers on each line or maybe put 2.5 in as a starting number and it will find out the next set of numbers ? Hope someone understand what i mean...?!

I tried putting them into Excel and graphing them and producing an equation but couldn't get a reliable fit.

Thanks
