Select the option in which numbers are related in the same way as are the numbers of following set.
(32, 54, 43)
Answer & explanation
Correct answer: option 1
(1st number + 2nd number) ÷ 2 = 3rd number
(32, 54, 43) → (32 + 54) ÷ 2 = \(\frac{86}{2}\) = 43
Similarly,
(31, 33, 32) → (31 + 33) ÷ 2 = \(\frac{64}{2}\) = 32
