Math question: What is the sum of all odd numbers between 2130 and 1 (inclusive)?

To find the sum of odd numbers from 2130 to 1, first, we need to find the number of odd numbers in this range and then calculate their sum. The number of odd numbers can be determined by finding the difference between the largest and smallest odd numbers and then adding 1. In this case, the largest odd number is 2129 and the smallest odd number is 1. So, the number of odd numbers is 2129 - 1 + 1 which equals 2129. To find the sum, we use the formula for the sum of an arithmetic series: S = (n/2)*(first term + last term). The first term is 1, the last term is 2129, and the number of terms (n) is 2129. Plugging these values into the formula, we get: S = (2129/2)*(1 + 2129) = 1138370. Therefore, the sum of all odd numbers between 2130 and 1 (inclusive) is 1,138,370.

Math question: What is the highest common factor (HCF) of 2130?

To find the HCF of 2130, we need to determine the largest number that can divide 2130 without leaving a remainder. Prime factorizing 2130, we get 2 * 3 * 5 * 71. Looking at these prime factors, we find that their common factor is only 1. So, the HCF of 2130 is 1 - no other number can evenly divide into 2130.

Math question: What is the sum of all the odd numbers from 1 to 2130? (Hint: Use the formula for the sum of an arithmetic series).

To find the sum of all odd numbers from 1 to 2130, we can first determine the number of terms. The largest odd number below or equal to 2130 is 2129. Now, 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 first term a = 1, the last term l = 2129, and the common difference d = 2 (since we are summing only odd numbers). We can calculate n = (l - a)/d + 1 = (2129 - 1)/2 + 1 = 1065. Finally, plugging these values into the formula, we have Sn = (1065/2)(1 + 2129) = 1,133,367. Therefore, the sum of all odd numbers from 1 to 2130 is 1,133,367.
