Math Question: What is the sum of the first 242 positive odd numbers?

To find the sum of the first 242 odd numbers, we need to consider the pattern. The first odd number is 1, the second odd number is 3, the third odd number is 5, and so on. We observe that these odd numbers are consecutive integers starting from 1. Therefore, we can use the formula for the sum of an arithmetic series: S = (n/2)(2a + (n-1)d), where S is the sum, n is the number of terms, a is the first term, and d is the common difference. Here, n = 242, a = 1, and d = 2 as the common difference between consecutive odd numbers is always 2. Plugging these values into the formula, we get S = (242/2)(2(1) + (242-1)(2)), simplifying to S = (121)(2 + 2(241)), further simplifying to S = 121(484), resulting in S = 58,604. Thus, the sum of the first 242 positive odd numbers is 58,604.

Math question: What is the sum of the digits in the number 242?

To find the sum of the digits in the number 242, we need to add up individual digits. Breaking down 242, we have 2 + 4 + 2 = 8. Thus, the sum of the digits in the number 242 is 8.

Math question: What is the sum of all the positive odd numbers less than 242?

To find the sum of all the positive odd numbers less than 242, we can use 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. The number of odd numbers less than 242 can be found by dividing 242 by 2 and rounding down, which is 120. Therefore, the last term is 241, as it is the largest odd number less than 242. Plugging these values into the formula, we get Sn = (120/2)(1 + 241) = 60 * 242 = 14520. Hence, the sum of all positive odd numbers less than 242 is 14520.
