The series you've provided is an infinite series of natural numbers:
\[ 1 + 2 + 3 + 4 + 5 + 6 + 7 + \dots \]
This series is known as the **sum of natural numbers**. However, it's important to note that this series **diverges** in the traditional sense. This means that as you keep adding more and more terms, the sum grows without bound and does not approach a finite limit.
### Mathematical Explanation:
The sum of the first \( n \) natural numbers is given by the formula:
\[
S_n = \frac{n(n + 1)}{2}
\]
As \( n \) approaches infinity (\( n \to \infty \)), the sum \( S_n \) also approaches infinity:
\[
\lim_{n \to \infty} S_n = \lim_{n \to \infty} \frac{n(n + 1)}{2} = \infty
\]
Therefore, the series \( 1 + 2 + 3 + 4 + \dots \) **does not converge** to a finite value in the conventional sense.
### Interesting Note:
In some advanced mathematical contexts, such as **zeta function regularization** or **Ramanujan summation**, the series \( 1 + 2 + 3 + 4 + \dots \) is assigned a finite value of \( -\frac{1}{12} \). However, this result is not a traditional sum and requires a different interpretation beyond standard summation methods.
\[
1 + 2 + 3 + 4 + \dots = -\frac{1}{12} \quad \text{(in certain advanced contexts)}
\]
But in the realm of standard calculus and series summation, the series diverges to infinity.
\[
\boxed{\infty}
\]
