The arithmetic sequence general formula is an = a1 + d *(n-1) where d is the arithmetic difference and n is an integer. In this case, upon derivation, the formula that represents the sum of the series is S = (a1 + an)*(n/2). Substituting, S = (3+75)*(10/2) equal to 390
The rate of change is 1.
Use the slope formula 5 - 0 is the rise and 5 - 0 is the run
5/5 = 1
