Correct Answer :

Option B

1096

Solution :

The correct answer is 1096.

To find the number that replaces the question mark (?) in the given series, let us analyze the pattern followed by the numbers:

7, 16, 43, 124, 367, ?

Method 1: Multiplying by 3 and subtracting 5

Each term in the series is obtained by multiplying the previous term by 3 and subtracting 5 from the result:

7×3-5=21-5=16

16×3-5=48-5=43

43×3-5=129-5=124

124×3-5=372-5=367

Applying the same logic to calculate the missing term (?):

367×3-5=1101-5=1096

Method 2: Adding consecutive powers of 3

Alternatively, we can examine the difference between consecutive terms:

16-7=9=32

43-16=27=33

124-43=81=34

367-124=243=35

The differences are increasing powers of 3 (32,33,34,35). Therefore, the next difference to add to 367 must be:

36=729

Adding this difference to 367 gives:

367+729=1096

Hence, the number that replaces the question mark (?) is 1096.
