Explanation:

Given

The above QBasic code

Required

The output

The iteration on the third line is repeated 5 times; i.e. for values of j from 1 to 5.

In each iteration, the value of N is printed and the next value is calculated.

Initially, the value of N is 1 ---- on line 2

So, 1 is printed first. The next value of N is as follows:

--- we keep replacing N (on the right-hand side) with current N value.

So, we have:
