Step-by-step Solution:

Correct Answer: B (112)

The solution is found by identifying the multiplication pattern in the sequence.

The rule is to multiply the current number by a multiplier that increases by 0.5 with each step (x1.5, x2, x2.5, x3, and so on).

• 5 × 1.5 = 7.5
• 7.5 × 2 = 15
• 15 × 2.5 = 37.5
• 37.5 × 3 = 112.5
• 112.5 × 3.5 = 393.75

According to the pattern, the term after 37.5 should be 112.5. The sequence lists it as 112, which is the wrong term.
