1 answers
The answer is the square of the first term minus the square root of the term. (9*9 = 81, 3*3 = 9, 81 - 3 = 78).Similarly, the square of 16 is 256. The square root of 16 is 4, therefore, the answer will be 256 - 4 = 252.
Alternative:
In 09 : 78 ,
⇒ 78 = (9 × 9) – (√9)
⇒ 81 – 3 = 78
Similarly,
In 16 : ?,
⇒ ? = (16 × 16) – (√16)
⇒ 256 – 4 = 252
Hence, 252 is correct option.Other Questions
