Directions: In the following question, a number sequence is given with one term missing. Choose the correct term that will continue the same pattern and replace the question mark in the given sequence.0,8,?,48,80,120

Correct answer: B. 24

  • A. 16
  • B. 24
  • C. -16
  • D. 32

Explanation

The sequence 0, 8, ?, 48, 80, 120 involves finding a pattern in the differences between consecutive terms. Calculating these differences gives us:8 - 0 = 8? - 8 = Difference 148 - ? = Difference 280 - 48 = 32120 - 80 = 40By observing the differences, we see the pattern involves adding terms that increase by a constant difference (8, 24, 32, 40). Therefore, the missing term must fit the pattern of increasing differences, which means the correct missing number is 24, resulting in the sequence: 0, 8, 24, 48, 80, 120. Thus, Option D (24) is correct because it aligns with this pattern.
