The correct option is C 33
The given pattern is 5, 12, 19, 26.
Difference between the first and the second terms = 12 - 5 = 7
Difference between the third and the second terms = 19 - 12 = 7
Hence, 7 should be added to a term to get the next term.
Now, the next term in the given pattern is 26 + 7 = 33
