Study the pattern carefully and find which of the following option will replace the missing term?
Answer
Correct Answer : d ) 12
Explanation :Observing the pattern in the columns of the table we get
The general logic for each column is
(Term in Row 1)2 – (Term in Row 2)3 = (Term in Row 3)
Therefore, for column I
(7)2 – (3)3 = 49 – 27 = 22 (Third term)
For column II
(22)2 – (7)3 = 484 – 343 = 141 (Third term)
Now, for column III
(45)2 – (X)3 = 297
X3 = 2045 – 297
X3 = 1728
X = 12
Hence, (d) is the correct answer.
