Answer:
A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1.Find a recursive formula. This example is an arithmetic sequence (the same number, 5, is added to each term to get to the next term).
Do y-y over x-x
So 10-4 = 6 and -7 - 1 = -8
6/-8 = -.75 is your slope
plug it into a y= Mx + b equation along with a y and x pair
4 = -.75(1)+ b
4 = -.75 + b
Solve the equation which gets you to b= 4.75
So y = -.75x+ 4.75 is your answer
