The terms of an arithmetic progression follow the relationship below:
ax = D*x + a0
We are told:
p = D*q + a0
q= D*p + a0
We can use elimination (subtraction of equations).
p - q = D*q - D*p
We can solve for D.
D = (p-q)/(q-p) = -1
We can determine a0.
p = -q + a0
a0 = p+q
Thus, for this arithmetic progression, the following relationship holds:
ax = -x + p + q
So,
ar = -r + p + q

That's all🙂
