Answer 1

Step-by-step explanation:

The assumptions made in interpolation and extrapolations are: There are no sudden jumps in the values of dependent variable(Y) from one period to another(X). The rate of change of figures (Y) from one period to another(X) is uniform. There will be no consecutive missing values in the series.
