Math question: Find the smallest prime number greater than 188 that is divisible by 5.

To find the smallest prime number greater than 188 that is divisible by 5, we first check multiples of 5 after 188. The next multiple of 5 is 190, which is not a prime since it is divisible by 2. The next multiple is 195, which is also not prime since it is divisible by 3. The next multiple is 200, which is divisible by 2, 5, and 10. However, it is not prime as it has multiple divisors. We continue checking multiples and find that the smallest prime greater than 188 and divisible by 5 is 205. Thus, the answer is 205.

Math question: What is the sum of all even numbers greater than 100 and less than 200?

To find the sum, we first list all even numbers between 100 and 200, which includes 102, 104, 106, ..., 198. Notice the sequence has a difference of 2 between consecutive numbers. We realize that it is an arithmetic sequence. The sum of an arithmetic sequence is given by the formula 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. We can easily calculate the values: a = 102, l = 198, and n = (l - a)/2 + 1 = (198 - 102)/2 + 1 = 49. Thus, the sum of all even numbers between 100 and 200 is Sn = (49/2)(102 + 198) = 49*300 = 14700. So, the answer to the math question is: The sum of all even numbers between 100 and 200 is 14700.

Math question: Find the sum of the prime numbers between 100 and 200, excluding the number 188.

To find the sum of the prime numbers between 100 and 200, we need to identify these primes and add them excluding 188. Starting from 101, we check each number for divisibility by primes less than its square root. The primes in this range are 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, and 199. However, 188 is not prime, so we exclude it. Calculating the sum of these primes, we have 101+103+107+109+113+127+131+137+139+149+151+157+163+167+173+179+181+191+193+197+199 = 2982. Hence, the sum of the prime numbers between 100 and 200, excluding 188, is 2982.
