Hope it helped :d
To find the common difference in the sequence 8, 16, 24, 32.... we must find what the difference between two consecutive terms is. A simple way to do this is to find the difference between the first term and the second term. That means that we have to do the second term - the first term. That means we do 16 - 8 which gives us that the common difference is 8.
So. We are going to take the first example which is -2. The rule is what your going to "plug" or put -2 into. So your equation should look like -2^2-5 (^2 is that exponent) put that into your calculator and you should get -9. That -9 is your Y value. Your -2 is your X value . So your ordered pair is (-2,-9) just repeat steps for -1, 0, and 1. Hope this helps!
