(7, 9, 11), (8, 10, 12), ?
Answer & explanation
Correct answer: option 3
\(\frac{I + III}{2}\) = \(\frac{7 + 11}{2}\) = 9
\(\frac{I + III}{2}\) = \(\frac{8 + 12}{2}\) = 10
Similarly,
\(\frac{I + III}{2}\) = \(\frac{6 + 18}{2}\) = 12
(7, 9, 11), (8, 10, 12), ?
Correct answer: option 3
\(\frac{I + III}{2}\) = \(\frac{7 + 11}{2}\) = 9
\(\frac{I + III}{2}\) = \(\frac{8 + 12}{2}\) = 10
Similarly,
\(\frac{I + III}{2}\) = \(\frac{6 + 18}{2}\) = 12
