## Function Table #1

Math brain teasers require computations to solve.

 Puzzle ID: #48226 Fun: (1.77) Difficulty: (2.37) Category: Math Submitted By: Magyk555 Corrected By: Magyk555

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)

 Magyk555 Nov 23, 2010 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. Part Two Of The Talk-Box Challenge: Now, go to my second I ever made. Magyk555 Nov 23, 2010 *Go to my second QUIZ I ever made. Sorry for the error! malliesmile Nov 24, 2010 clever teaser but i think the last one (100-->316) is incorrect.. i think B should be 318. Magyk555 Nov 24, 2010 It is correct because 100x3.14=314. Then add 2. It equals 316. eddandi Mar 31, 2011 the following formula works as well 3.14(x-1)+5.14
