45, 39, 33, 27, 21, ...
(18 + 36) + (45 - 27) = 54 + 18 = 72
The halfway value is (27 + 45)/2 = 72/2 = 36
187 − 45 = 142
First you take the difference between the numbers (45 - 18 = 27). Then take that number and divide it by the original number. So 27/18 = 1.5 Then multiply by 100 for the percent. 1.5 x 100 = 150%.

The GCF is 9.
The halfway value is (27 + 45)/2 = 72/2 = 36
The difference between the two is 179, since -45 + 45 equals 0 and added on to 134 gives you a total of 179.
