1. ## Number Growth Help

OK, i have two data sets, one is an Input, one is an output

As the Input Grows, the output grows at a faster rate
EG
at 225 the output is 18.92 or 8.41% of the Input
at 254.25 the output is 23.31 or 9.17% of the Input
it keeps on like this until you reach
355 input with an output of 38.5 or 10.83%

How would i go about finding the a formula to solve for the unknown?

Thanks for the Help
Kevin

Plot the data, you will find the points lie exactly on a line. The general equation of a line is:

y=mx+c,

where x is the input and y the output.

Chose any two points from your data set (say the first and last) to get:

18.92=225m+c

and

38.8=355m+c.

Then solve for m and c.

3. Thanks, That was close, but as the data Grows, so does the deviation, i will continue to play with the formula's

The points you gave lie exactly (or as near as makes no difference) on a
straight line. There is nothing in your data to indicate or justify any other
model.
