Question: What is the sum of the first 50 odd numbers starting from 1015?

To find the sum of the first 50 odd numbers starting from 1015, we can use the formula for the sum of an arithmetic series. The first term is 1015, and since odd numbers increase by 2, the common difference is 2. We can apply the formula: Sn = (n/2)(2a + (n-1)d), where Sn is the sum, a is the first term, n is the number of terms, and d is the common difference. Plugging in the values, we get Sn = (50/2)(2*1015 + (50-1)*2) = (25)(2030 + 98) = 25*2128 = 53,200. Hence, the sum of the first 50 odd numbers starting from 1015 is 53,200.

What is the largest three-digit number that is divisible by 5 and 7, but not by 3 or 11?

To find the largest three-digit number, we start by listing the three-digit numbers that are divisible by 5 and 7. We observe that the least common multiple of 5 and 7 is 35. So, we need to find the largest multiple of 35 that is less than 1000. By dividing 1000 by 35, we get 28 with a remainder of 20. Since we're looking for the largest number, we multiply 28 by 35, giving us 980. However, this number is divisible by 3. Therefore, we subtract 35 from 980 to get 945. Again, this number is divisible by 11, so we subtract another 35. Finally, we obtain the largest three-digit number satisfying the conditions: 945.

Math question: If 1015 is multiplied by 7 and then divided by 5, what is the remainder when this result is divided by 13?

To solve this, we multiply 1015 by 7, getting 7105. Then, we divide 7105 by 5, which gives us 1421. Finally, dividing 1421 by 13, we find that the remainder is 12. Therefore, the remainder when 1015 is multiplied by 7 and divided by 5, then divided by 13 is 12.
