A function table is a table of order pairs that follow a rule. A rule tells how one number is related to another. In this brainteaser, I will give you a function table (sometimes called an input-output table) and you need to figure out what the rule is. I will give you an example.

Example:

Input(A), Output(B)
7(A), 9(B)
13(A), 15(B)
1(A), 3(B)
3(A), 5(B)
9(A), 11(B)
The rule in this example is add 2. Now here is the real deal. Find out what the rule is.
*This one will be harder than the example. Way harder.

Input(A), Output(B)
7(A), 23.98(B)
13(A), 42.82(B)
39(A), 124.46(B)
1(A), 5.14(B)
100(A), 316(B)

Sorry guys about the bad brainteaser! I am trying to submit a correction to specify which humber is A and which one is B. I am also trying to seperate the numbers with a comma.

This is for my talk-box challenge.

clever teaser
but i think the last one (100-->316) is incorrect.. i think B should be 318.

It is correct because 100x3.14=314. Then add 2. It equals 316.

the following formula works as well

3.14(x-1)+5.14
