![**Question:**
Find the sum of all the natural numbers from 1 to 21 (Thanks to Induction this is easy!)
- ⓞ 350
- ⓞ 420
- ⓞ 105
- ⓞ 210
**Explanation:**
This question asks for the sum of the natural numbers from 1 to 21. By using mathematical induction, or a simpler formula for the sum of an arithmetic series, this task can be simplified. The formula for the sum of the first \( n \) natural numbers is:
\[ S = \frac{n(n + 1)}{2} \]
By plugging \( n = 21 \) into the formula, you can find the correct answer from the options provided.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa35f92df-3337-4fc2-85e4-1050e148fe29%2F620e2f5e-dee5-468c-96b7-7bebe69253f4%2F6spc132_processed.png&w=3840&q=75)
