Find the missing term.
119, 109, 89, 59, ______
- A19
- B39
- C49
- D29
Solution & Step-by-step Explanation
Let's find the difference between consecutive terms in the series:
119−109=10
109−89=20
89−59=30
The differences are increasing multiples of 10: 10,20,30. Following this pattern, the next difference must be 40.
Missing term=59−40=19
119−109=10
109−89=20
89−59=30
The differences are increasing multiples of 10: 10,20,30. Following this pattern, the next difference must be 40.
Missing term=59−40=19
