In a geometric sequence, the_between consecutive terms is constant.

In a geometric sequence, the common ratio between consecutive terms is constant.

Step-by-step explanation:

In a geometric sequence, the common ratio between consecutive terms is constant.

The n-th term of a geometric sequence with first term and common ratio is represented by the formula:

For example,

As the common ratio 'r' between consecutive terms is constant.

So, the common ratio between consecutive terms is constant i.e. -3. Thus, it is a geometric sequence with a common ratio -3.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
