Find the solution to the recurrence relation an = an - 1 + 3 with the initial condition a0 = 1 using an iterative approach.

The solution of the recurrence relation is given by and this can be determined by using the arithmetic operations.

Given :

In order to determine the solution of the recurrence relation, substitute (n = 1) in the given relation.

Now, substitute the value of (n = 2) in the given relation.

Now, substitute the value of (n = 3) in the given relation.

So, from the above calculation, it can be concluded that the solution of the recurrence relation is given by:
