Math question: What is the sum of all positive odd numbers less than or equal to 3?

To find the sum of positive odd numbers up to 3, we consider the sequence of odd numbers starting from 1. The odd numbers less than or equal to 3 are 1 and 3. Adding them together gives us (1 + 3) = 4. Therefore, the sum of all positive odd numbers less than or equal to 3 is 4.

Math question: What is the sum of the first 100 positive odd numbers, starting from 3?

To find the sum of the first 100 positive odd numbers, we can use the arithmetic series formula. The first term, a = 3, and the common difference, d = 2 since we are dealing with odd numbers. The formula for the sum of an arithmetic series is Sn = (n/2)(2a + (n-1)d), where n represents the number of terms. Substituting the given values, we have Sn = (100/2)(2(3) + (100-1)(2)) = 50(6 + 198) = 50(204) = 10200. Therefore, the sum of the first 100 positive odd numbers starting from 3 is 10200.

Math question: What is the sum of all even numbers from 1 to 3?

To find the sum of even numbers from 1 to 3, we need to determine which numbers are even in this range. Out of the numbers 1, 2, and 3, only number 2 is even. Thus, the sum of all even numbers from 1 to 3 is 2.
