The d value is going to be -3 because you have to compute the differences of all the adjacent terms. 2-5=-3 -1-2=-3 -4-(-1)=-3 -7-(-4)=-3 The difference between all the adjacent terms is the same and equal to -3
I looked at another online and it said letter A. (Not 100% sure)
You divide 162 and it equals to 81
I think it’s 6
Sorry if I’m wrong
