SolutionFirst, we take the numbers in P. If we add the left number and the right number, we get â 21 24 = 45 If we add the top number and the bottom number, we get â 8 9 = 17 Now, if we subtract these two numbers â 45 â 17 = 28 â we get the middle number. Letâs check in numbers in R has the same pattern. If we add the left number and the right number, we get â 29 35 = 64 If we add the top number and the bottom number, we get â 9 10 = 19 Now, if we subtract these two numbers â 64 â 19 = 45 â we get the middle number. That means the numbers in Q will follow the same pattern. Letâs add the left and the right numbers - 23 42 = 65 Letâs add the top and the bottom numbers â 11 12 = 23. Letâs subtract these two numbers â 65 â 23 = 42 That means 42 will be the middle number in Q. Option B is the right answer.
