Three is the first number of a pair, and 8 is the second. 4-11 5-14 6-17 ____ ____ ____ 10-29 ____ ____ ____ Hi Terry,
If you look at the string of second numbers, Check the next 4 pairs that have first numbers 7, 8, 9 and 10 to make sure that the "add 3" procedure gives the pair 10-29.
Now that you see that "add 3" is the procedure, look again at the pairs. Notice that in each case the second number is almost 3 times the first number. In fact each second number is one less than 3 times the first number. 11 is 1 less than 3 times 4 14 is 1 less than 3 times 5 17 is 1 less than 3 times 6 Penny
