What should come in place of the question mark (?) in the given series?
160,187,216,247,?
- A290
- B280
- C209
- D208
Solution & Step-by-step Explanation
Let's find the difference between consecutive terms of the given series:
187−160=27
216−187=29
247−216=31
The differences between successive terms are consecutive odd numbers: 27,29,31.
Following this pattern, the next difference must be 33.
Next term=247+33=280
187−160=27
216−187=29
247−216=31
The differences between successive terms are consecutive odd numbers: 27,29,31.
Following this pattern, the next difference must be 33.
Next term=247+33=280
