The problem asks for the output of the given flowchart. The flowchart initializes $x$ to 1 and $T$ to 1. It then checks if $x > 5$. If it is, the flowchart stops. Otherwise, it displays $T$, increments $x$ by 1, calculates $T$ as $T+x$, and repeats the loop.

1. Problem Description
The problem asks for the output of the given flowchart. The flowchart initializes to 1 and to
1. It then checks if $x > 5$. If it is, the flowchart stops. Otherwise, it displays $T$, increments $x$ by 1, calculates $T$ as $T+x$, and repeats the loop.
2. Solution Steps
We will trace the execution of the flowchart.
- Initially, and .
- The condition (i.e., ) is false.
- Display , which is
1. - $x$ becomes $x + 1 = 1 + 1 = 2$.
- becomes .
- The condition (i.e., ) is false.
- Display , which is
3. - $x$ becomes $x + 1 = 2 + 1 = 3$.
- becomes .
- The condition (i.e., ) is false.
- Display , which is
6. - $x$ becomes $x + 1 = 3 + 1 = 4$.
- becomes .
- The condition (i.e., ) is false.
- Display , which is
1
0. - $x$ becomes $x + 1 = 4 + 1 = 5$.
- becomes .
- The condition (i.e., ) is false.
- Display , which is
1
5. - $x$ becomes $x + 1 = 5 + 1 = 6$.
- becomes .
- The condition (i.e., ) is true.
- The flowchart stops.
The output is the sequence of values of that are displayed: 1, 3, 6, 10, 15,
