What is the smallest prime number greater than 7157?

The smallest prime number greater than 7157 is 7177. To determine this, we start by checking if 7157 is a prime number. By checking divisibility, we find that 7157 is only divisible by 1 and itself, confirming its primality. We then increment 7157 by 1 to find the next number, 7158, which is not prime. Continuing this process, we quickly find that 7177 is the smallest prime number greater than 7157.

Math question: If the number 7157 represents the sum of three consecutive odd numbers, what are the numbers?

Let's assume the first odd number is x. Therefore, the next consecutive odd numbers would be x + 2 and x + 4. According to the given information, the sum of these three numbers is equal to 7157. So we can write the equation as: x + (x + 2) + (x + 4) = 7157. Simplifying further, 3x + 6 = 7157. By subtracting 6 from both sides, we get 3x = 7151. Dividing both sides by 3, we find x = 2383. Hence, the three consecutive odd numbers are 2383, 2385, and 2387, which add up to 7155, not 7157. Therefore, it seems there may be a mistake in either the provided number or the problem statement.

Math Question: What is the sum of the thousands digit, multiplied by the hundreds digit, added to the tens digit, and subtracted from the units digit of the number 7157?

To find the solution, we break down the number 7157. The thousands digit is 7, hundreds digit is 1, tens digit is 5, and the units digit is 7. So, (7 * 1000) + (1 * 100) + 5 - 7 = 7000 + 100 + 5 - 7 = 7114. Therefore, the sum is 7114.
