Difficulty: Easy
Correct Answer: 1.5
Explanation:
Introduction / Context:This series uses gradually increasing fractional multipliers, rising by 1/4 each time.
Given Data / Assumptions:
Concept / Approach:Verify each transition as a multiplication by the stated fractions.
Step-by-Step Solution:
16 × 1/4 = 44 × 1/2 = 22 × 3/4 = 1.51.5 × 1 = 1.5 → missing term1.5 × 5/4 = 1.875 ✔Verification / Alternative check:The fractional ladder 0.25, 0.5, 0.75, 1.0, 1.25 precisely fits all steps.
Why Other Options Are Wrong:2 or 1.75 would break the uniform increment of 1/4 in the multipliers.
Common Pitfalls:Confusing additive with multiplicative growth; here it is strictly multiplicative.
Final Answer:1.5.
