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.71,25,83,37,95,49,?
Correct answer: B. B: 107
- A. A: 61
- B. B: 107
- C. C: 59
- D. D: 105
Explanation
The given sequence is: 71, 25, 83, 37, 95, 49, ?Separate the sequence into two alternating patterns:1st, 3rd, 5th terms: 71, 83, 952nd, 4th, 6th terms: 25, 37, 49Pattern 1 (71, 83, 95):The difference is consistently 12 (83 - 71 and 95 - 83). Thus, the next number is 95 + 12 = 107.Pattern 2 (25, 37, 49):The difference is also 12 (37 - 25 and 49 - 37), but this pattern does not continue at the seventh position.Therefore, the missing number is 107, following the first pattern.Options 61 and 59 do not fit the required pattern, and 105 does not match the consistent difference of 12 in the sequence.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
