First, calculate the equivalent periodic payment of R2833 using the formula for the present value of an ordinary annuity:
PV = R * [(1-(1 + r)^-n)/r]
where PV is the present value of the payments, R is the periodic payment, r is the periodic interest rate, and n is the total number of periods.
Given that PV = R2833, r = 0.18/6 = 0.03, and n = 3*6 = 18, we can substitute these values into the formula:
2833 = R * [(1-(1 + 0.03)^-18)/0.03]
2833 = R * [(1-0.606477)/0.03]
2833 = R * (0.393523/0.03)
2833 = R * 13.1174
R = 2833 / 13.1174
R ≈ 215.973
Therefore, the periodic payment of the series of payments is approximately R215.97 every second month.
