Understanding the Sequence
To solve the expression 1 + 2 + 1, we need to recognize the pattern in the sequence of numbers provided. The numbers are arranged in a manner that resembles an up-and-down pattern.
Breaking Down the Pattern
- The first number is 1.
- The second number increases to 2 (up).
- The third number decreases back to 1 (down).
Calculating the Sum
Now, let's add these numbers together:
- Start with 1.
- Add 2:
- 1 + 2 = 3.
- Finally, add the last 1:
- 3 + 1 = 4.
So, the total sum of 1 + 2 + 1 is 4.
Conclusion
The correct answer is option 'B', which is 4. This showcases how understanding patterns in sequences can help simplify calculations and identify the right answers easily.
