Question: Determine the sum of all odd numbers between 3958 and 1, inclusively.

To find the sum, first, calculate the number of odd terms using the formula (a - b) / 2 + 1, where a = 3958 and b = 1. Applying this, we get (3958 - 1) / 2 + 1 = 1979 odd numbers. The sum of an arithmetic progression is given by Sn = (n/2)(2a + (n-1)d), where n is the number of terms, a is the first term, and d is the common difference. Substituting values, Sn = (1979/2)(3958 + (1979-1)(2)) = (1979/2)(3958 + 3956) = 1979/2 * 7914 = 7,832,463. Thus, the sum of all odd numbers between 3958 and 1 is 7,832,463.

Math Question: What is the sum of the digits of the number 3958 multiplied by their respective place values?

For the number 3958, the sum of the digits multiplied by their place values can be calculated as follows: 3 x 1000 + 9 x 100 + 5 x 10 + 8 x 1 = 3000 + 900 + 50 + 8 = 3958. Thus, the sum of the digits 3, 9, 5, and 8 multiplied by their respective place values is equal to the number 3958 itself.

Math question: What is the sum of the digits in the number 3958?

To find the sum of the digits in the number 3958, we add the individual digits together. 3 + 9 + 5 + 8 = 25 Therefore, the sum of the digits in the number 3958 is 25.
