Which term denotes a sequence showing gradual change in size or magnitude?

• A. Gradation
• B. Proportion
• C. Population trends
• D. Real estate data to examine

Answer: (A)

Gradation captures a sequence that changes gradually in size or magnitude along a scale. It implies small, incremental steps from one value to the next, creating a smooth progression—like a color fade, a series of garment sizes, or any measurement that shifts little by little. This is exactly what “a sequence showing gradual change” means.

Proportion, by contrast, is about the relationship between parts of a whole, not a step-by-step change over a scale. Population trends describe how population figures change over time, which is about patterns in data rather than a single gradual progression on a scale. “Real estate data to examine” isn’t a standard term for gradual change either, so it doesn’t fit the idea as precisely.
