Select the correct option that will fill in the blank and complete the series.
43, 55, 79, 115, ______
- A163
- B127
- C172
- D139
Solution & Step-by-step Explanation
Let's calculate the difference between consecutive terms:
55−43=12
79−55=24
115−79=36
The differences are consecutive multiples of 12 (12×1,12×2,12×3). Following this logic, the next difference must be:
12×4=48
Now, add this difference to the last term to find the missing value:
Missing Term=115+48=163
55−43=12
79−55=24
115−79=36
The differences are consecutive multiples of 12 (12×1,12×2,12×3). Following this logic, the next difference must be:
12×4=48
Now, add this difference to the last term to find the missing value:
Missing Term=115+48=163
