A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
80, 130, 190, 260, ?
- A350
- B340
- C300
- D320
Solution & Step-by-step Explanation
Let's check the differences between consecutive terms:
130−80=50
190−130=60
260−190=70
The differences are increasing by 10 each time (50,60,70). Therefore, the next difference must be 80.
Next term=260+80=340
130−80=50
190−130=60
260−190=70
The differences are increasing by 10 each time (50,60,70). Therefore, the next difference must be 80.
Next term=260+80=340
