Is the number increasing or decreasing?
Then do the inverse operation. Such as:
The example you give above, the numbers are increasing (adding) so to find the sequence, use minus. So now to solve the problem, you have to go backward. Such as 6 minus the number back of it so, 6-4.95=1.41. This means to get 4.95 to 6 is 1.41. And then do the next step the same thing. If you end up more than two sequel, it's okay. Just say (Example)> The sequel it is going back 5.87 and 5.89.
