Math question: What is the sum of the first 881 odd natural numbers?

To find the sum of the first 881 odd natural numbers, we can notice that the nth odd number is given by the formula 2n-1. Thus, the sum can be calculated as (1 + 3 + 5 + ... + 2n-1). Using the formula for the sum of an arithmetic series, 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, we can find the value. Here, n = 881, a = 1, and l = 2(881) - 1 = 1761. Plugging these values into the formula, the sum is (881/2)(1 + 1761) = 388,221. So, the sum of the first 881 odd natural numbers is 388,221.

Question: If the number 881 is multiplied by 7 and then divided by 11, what is the result?

To find the result, we first multiply 881 by 7, which gives us 6167. Then, we divide 6167 by 11 to obtain the final result. After performing the division, the answer is approximately 560. This means that when multiplying 881 by 7 and dividing the product by 11, the result is around 560.

What is the sum of all even numbers from 2 to 881?

To find the sum of even numbers up to 881, we use the formula for the sum of an arithmetic series: (n/2)(first term + last term). The first even number is 2, and the last even number smaller than or equal to 881 is 880. Plugging these values into the formula, we get (440)(2 + 880) = 385,120. Therefore, the sum of all even numbers from 2 to 881 is 385,120.
