210, 228, 250, 274, 302, 332, 365
Correct Answer :
365
Solution :
The correct option is 365.
To identify the wrong number in the given series, let us analyze the differences between consecutive terms.
Given series: 210, 228, 250, 274, 302, 332, 365
Let us find the difference between consecutive numbers:
Now, let us examine the pattern of differences:
The difference increases alternatingly or follows a prime/even pattern based on adding numbers or consecutive even additions. Specifically, looking at the logic of adding prime numbers or consecutive even numbers after specific pattern increments:
Notice the differences: 18, 22, 24, 28, 30...
The sequence of differences increases by +4, +2, +4, +2...
Checking the pattern of differences:
18 + 4 = 22
22 + 2 = 24
24 + 4 = 28
28 + 2 = 30
30 + 4 = 34
According to this (+4, +2, +4, +2, +4...) pattern of differences, the next difference should be 34 instead of 33.
Therefore, the expected last term is:
Hence, 365 is the wrong number in the given series as it should be replaced by 366.
