Finding the Missing Number in the Series
Given series: 3, 9, 24, 57, ?, 267, 552
To find the missing number in the series, we need to identify the pattern followed in the given series. Let's analyze the series step by step:
Step 1: The difference between the first two terms is (9-3) = 6.
Step 2: The difference between the second and third terms is (24-9) = 15.
Step 3: The difference between the third and fourth terms is (57-24) = 33.
Step 4: The difference between the fourth and fifth terms is (?-57).
Step 5: The difference between the fifth and sixth terms is (267-?) = (552-267) = 285.
Step 6: The difference between the sixth and seventh terms is (552-267) = 285.
From the above analysis, we can observe that the differences between the consecutive terms of the series are increasing by a constant difference. Therefore, the missing number in the series can be calculated as follows:
The difference between the fourth and fifth terms is (57-24) = 33.
So, the difference between the fifth and sixth terms should be (33+15) = 48.
Therefore, the missing number in the series is (57+48) = 105.
Hence, the correct answer is option 'B' (126).

The pattern is x2+3,x2+6,x2+9,x2+12
hence the answer is 126
what you have to do is multiply the term and add multiples of 3
i.e 3x2+3=9
9x2+6=24
24x2+9=57
57x2+12=126
