So it takes him 45 minutes to mow 0.6 of an acre
It will take him 85 minutes to mow an acre
The sum of the arithmetic series has a formula of
S = (n/2)(a₁ + aₙ)
where
n = number of terms
a₁ = first term
aₙ = last term or nth term
Given n = 50, a₁ = -13, aₙ = 134. The sum is
S = (50/2)(-13 + 134)
S = 3025 (ANSWER)
