Solution:
The pattern in the given series is not apparent immediately. However, we can find the pattern by looking at the differences between consecutive terms.
First Difference: 7, 8, 22, ?, ...
The first difference between the consecutive terms of the given series is obtained by subtracting the second term from the first, the third term from the second, and so on. This gives us the following series of differences:
7, 8, 22, ...
The pattern in this series is not immediately apparent. However, we can find the pattern in the second differences.
Second Difference: 1, 14, ?, ...
The second difference between the consecutive terms of the series of differences is obtained by subtracting the second term from the first, the third term from the second, and so on. This gives us the following series of second differences:
1, 14, ...
The pattern in this series is that the terms are increasing by 13.
Therefore, the missing term in the series is obtained by adding 35 to the previous term.
Missing Term: 41 + 35 = 76
Therefore, the answer is option (b) 79.
