Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(14, 10, 9)
(6, 8, 2)
(8, 4, ?)
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed).
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 6.
The Logic is : (First Number - Third Number) = Second Number ÷ 2
⇒(14, 10, 9)
14 - 9 = 10 ÷ 2
5 = 5
⇒(6, 8, 2)
6 - 2 = 8 ÷ 2
4 = 4
Similarly,
⇒(8, 4, ?)
8 - a = 4 ÷ 2
a = 6
Hence, 6 is the correct answer.
