Question
Which of the following numbers will replace the question
mark (?) in the given series? 144, 169, 196, ?, 256, 289, 324Solution
The logic followed here is: The square of the consecutive number in the number series is the next number starting from '12'. 12² = 144 13² = 169 14² = 196 15² = 225 16² = 256 17² = 289 18² = 324
48 24 24 48 ? 1536
