Math question: What is the largest prime number smaller than 7918?

To find the largest prime number smaller than 7918, we must test all numbers from 7917 backwards. Starting from 7917, we divide it by all numbers less than its square root, checking if it's divisible by any of them. After testing, we find that 7919 is the largest prime number smaller than 7918. The process involves sequentially dividing 7917 by numbers from 2 to 88, as the square root of 7917 is approximately 88.9. Since 7919 is not divisible by any number from this range, it is the largest prime number smaller than 7918.

What is the sum of the digits of the odd number greater than 7000 and less than 8000, whose thousandth digit is one more than the hundredth digit and tens digit is half of the unit digit, while hundreds digit is three times the thousands digit?

Let's break down the number 7918. The thousandth digit is 7, the hundredth digit is 9, the tens digit is 1, and the unit digit is 8. According to the conditions given, we have: - Thousandth digit: 7 - Hundredth digit: 9 - Tens digit: Half of unit digit, so 1 - Hundreds digit: Three times the thousands digit, so 21 (3 * 7) Now, let's calculate the sum of these four digits: 7 + 9 + 1 + 21 = 38 Therefore, the sum of the digits of the number 7918 is 38.
