Concept:This is a number analogy where the second number is obtained by subtracting the next prime number from the square of the first number.Explanation:For the pair 7:38, the first number is 7.The next prime number after 7 is 11.So, 72−11=49−11=38.Apply the same rule to 16.The next prime number after 16 is 17.Therefore, 162−17=256−17=239.Thus, the missing number is 239, which matches option C.Answer:The correct answer is option C, 239.
