Antecedent is the first term in a ratio .
Well, well, well, look who's getting fancy with geometric sequences! When the ratio between consecutive terms is "r," each term is found by multiplying the previous term by "r." So, in simpler terms, if you have a sequence like 2, 4, 8, 16, the ratio between consecutive terms is 2. Math can be sassy too, honey!
The numerator of the second ratio and the denominator of the first ratio are called the means, and the numerator of the first ratio and the denominator of the second ratio are called the extremes. The product of the means equals the product of the extremes.
As 21 is 3 x 7 the ratio 7:21 = 1:3
Expressed as a ratio in its simplest terms, 105:150 is equal to 7:10, or seven to ten.
I guess you mean the ratio of the areas; it depends if the 2 rectangles are "similar figures"; that is their matching sides are in the same ratio. If they are similar then the ratio of their areas is the square of the ratio of the sides.
A ratio is a comparison of two quantities. When the second term of a ratio is 100, it means that the ratio is comparing the first term to 100. For example, if the ratio is 1:100, it means the first term is 1 and the second term is 100. Ratios with a second term of 100 are often used to express proportions or percentages.
It is a*r^4 where a is the first term and r is the common ratio (the ratio between a term and the one before it).

You start with the number 4, then multiply with the "common ratio" to get the next term. That, in turn, is multiplied by the common ratio to get the next term, etc.

Divide any term, except the first, by the term before it.
It is 1062882.
Find the 7th term of the geometric sequence whose common ratio is 1/2 and whose first turn is 5
The use of the expression 'common ratio' means that the sequence is a Geometric series where the terms are of the form a, ar ar2, ar3, ...arn-1 where a is the first term and r is the common ratio. The third term, a3 = 3 x 32 = 3 x 9 = 27
