Find the missing term in the sequence: 0, 7, 15, 24, 34, ?
Correct answer: B. 45
- A. 55
- B. 45
- C. 46
- D. 50
Explanation
The pattern is n² - 1, starting with n=1. 1²-1=0, 3²-2=7, 4²-1=15, 5²-1=24, 6²-2=34. Correction: The pattern seems inconsistent. A simpler pattern is the difference between terms increases by 1: +7, +8, +9, +10. The next difference should be +11, so 34 + 11 = 45.
