In the following question, select the missing number from the given series.
57, 69, 81, 93, ?, 117
- A104
- B105
- C111
- D108
Solution & Step-by-step Explanation
Let us verify the difference between consecutive numbers:
69−57=12
81−69=12
93−81=12
The series increases by a constant common difference of +12.
Missing number=93+12=105
Let us cross-verify with the last term: 105+12=117, which matches.
69−57=12
81−69=12
93−81=12
The series increases by a constant common difference of +12.
Missing number=93+12=105
Let us cross-verify with the last term: 105+12=117, which matches.
