Consider a periodic annuity whose payment is semestral 189.5 euro for 2 years and then monthly 10.7 euro for the next year.

Compute its value at the end of the first year, knowing that the two-monthly intensity of the interest is 3.2% in the first semester, it is null in the next 3 months and then it is semestral and equal to S^2(t) = (0.2/(1+0.01t))
