Substitute in the values for y and x into the equation.
so..
8 - 4.7(-1) - (2) solve the equation
8 + 4.7 -2
12.7 - 2
10.7
The equation would be .05x+50=100 Then you would solve for x
The equation is: 27.46 = 1.95x + 2.50
The answer is 12.8
The common difference, d, is 5 and the starting value, a, is 2.
