Math question: What is the sum of all the positive integers from 1 to 2007?

To find the sum of all positive integers from 1 to 2007, we can use the formula for the sum of an arithmetic series: Sn = (n/2) * (a1 + an) Where Sn is the sum, n is the number of terms, a1 is the first term, and an is the last term. In this case, since we want to find the sum up to 2007, a1 = 1, an = 2007, and we need to find the number of terms (n). We can calculate n using the formula: an = a1 + (n - 1) * d 2007 = 1 + (n - 1) * 1 2006 = (n - 1) n = 2007 Plugging these values into the sum formula: Sn = (n/2) * (a1 + an) Sn = (2007/2) * (1 + 2007) Sn = 1003.5 * 2008 Sn = 2,014,426 Therefore, the sum of all positive integers from 1 to 2007 is 2,014,426.

Question: What is the sum of all positive odd integers less than 2007?

To find the sum of all positive odd integers less than 2007, we first identify the first odd number, which is 1, and the last odd number less than 2007, which is 2005. The numbers in this sequence form an arithmetic progression with a common difference of 2. We can use the arithmetic series formula, Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, n = (2005 - 1)/2 + 1 = 1003. Plugging in the values, we get Sn = (1003/2)(1 + 2005) = 503 * 2006 = 1,008,518. Thus, the sum of all positive odd integers less than 2007 is 1,008,518.

Math question: What is the sum of the odd numbers from 1 to 2007 inclusively?

To find the sum of odd numbers from 1 to 2007, we can use the formula for the sum of an arithmetic sequence, Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. First, we find the number of terms: 2007 is an odd number, so there are (2007+1)/2 = 1004 odd terms from 1 to 2007. Next, we find the first and last terms: The first term, a, is 1, and the last term, l, is 2007. Now we can plug these values into the formula to find the sum: Sn = (1004/2)(1 + 2007) = 502 * 2008 = 1006016. Therefore, the sum of the odd numbers from 1 to 2007 inclusively is 1,006,016.
