Answer 2

100(100+1)/2= 5050

Answer 3

To understand how Carl found the answer, we can look for a pattern in the numbers from 1 to 100. One approach is to group the numbers into pairs that sum up to 101: 1 + 100, 2 + 99, 3 + 98, and so on. So, we have 50 pairs of numbers that sum up to 101.

Since we have 50 pairs, we can multiply 50 by 101. Therefore, the answer is 50 multiplied by 101, which equals 5,050.

So, to find the sum of all the numbers from 1 to 100, Carl likely noticed the pattern of pairing the numbers to get a sum of 101 and then multiplied the number of pairs by 101. The correct answer is 5,050.
