1. Problem Description

The problem presents a Pascal program segment that initializes and modifies an array named numnum. The program then iterates through a loop and outputs the elements of the array from index 1 to

5. We are asked to determine what the output of the program will be.

2. Solution Steps

First, let's trace the execution of the program and track the values of the array elements:
* `Num[0] := 8;` sets Num[0]=8Num[0] = 8.
* `Num[3] := 20;` sets Num[3]=20Num[3] = 20.
* `Num[5] := Num[3] - 5;` sets Num[5]=205=15Num[5] = 20 - 5 = 15.
* `Num[2] := Num[0] + 5;` sets Num[2]=8+5=13Num[2] = 8 + 5 = 13.
* `Num[1] := Num[0] + Num[3];` sets Num[1]=8+20=28Num[1] = 8 + 20 = 28.
* `Num[4] := Num[5] * 2;` sets Num[4]=152=30Num[4] = 15 * 2 = 30.
The program then enters a `For` loop that iterates from `count = 1` to `count = 5`. Inside the loop, it outputs the value of `Num[count]` for each iteration. Therefore, the program will print the following:
* `count = 1`: prints Num[1]=28Num[1] = 28.
* `count = 2`: prints Num[2]=13Num[2] = 13.
* `count = 3`: prints Num[3]=20Num[3] = 20.
* `count = 4`: prints Num[4]=30Num[4] = 30.
* `count = 5`: prints Num[5]=15Num[5] = 15.

3. Final Answer

The output of the program is:
```
28
13
20
30
15
```
