    A 43 - 1854 Correct Answer Incorrect Answer
    B 36 - 1301 Correct Answer Incorrect Answer
    C 24 - 581 Correct Answer Incorrect Answer
    D 18 – 332 Correct Answer Incorrect Answer

    Solution

    5 is added to the square of the first number to get the second number. 1) 43 - 1854→ 43² + 5 = 1849 + 5 = 1854. 2) 36 - 1301→ 36² + 5 = 1296 + 5 = 1301. 3) 24 - 581→ 24² + 5 = 576 + 5 = 581. 4) 18 – 332→ 18² + 5 = 324 + 5 = 329.
