Ratio
A ratio is a comparison of two quantities that are directly related. For example, if you have 3 apples and 6 oranges, the ratio of apples to oranges is 3:6. This means that for every 3 apples there are 6 oranges.
Proportion
A proportion is a ratio that is equal to a given constant. For example, if the ratio of apples to oranges is 3:6, the proportion of apples to oranges is also 3:6. This means that no matter what the size of the apples or oranges, the proportion will always be the same.
Successive Variation
Successive variation is a pattern of numbers in which the difference between consecutive numbers increases or decreases in a consistent manner. For example, the following sequence of numbers shows a pattern of successive variation:
3, 5, 7, 9, 11
In this sequence, the difference between consecutive numbers increases by 2, resulting in a pattern of successive variation
