What is the sum of integers from 1 to 100?
ZERO POINT — 0 entries (structural invariants)
UNOBSERVED — 0 entries (implied truths)
OBSERVED — 0 entries (explicit in request)
COMPLEXITY │ 0 entries │ spread: 0° │ band: LOW
Baseline response (no ZPI)
**Sum of Integers from 1 to 100**
The sum of integers from 1 to 100 can be calculated using the formula for the sum of an arithmetic series:
**Formula:** `sum = (n * (a1 + an)) / 2`
Where:
- `n` is the number of terms (100 in this case)
- `a1` is the first term (1)
- `an` is the last term (100)
**Calculation:**
```csharp
int n = 100;
int a1 = 1;
int an = 100;
int sum = (n * (a1 + an)) / 2;
Console.WriteLine(sum);
```
**Result:** The sum of integers from 1 to 100 is **5050**.
