Which sequence are geometric? check all that apply

The sequences are geometric,

10, 7.5, 5.625, 4.28175,

160, 40, 10, 2.5,

20, 70, 245, 857.5,

20, 70, 245, 857.5

5, 5.5, 6.05, 6.655

We have to determine, which sequences of the following series are geometric,

According to the question,

A geometric sequence is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r.

To find the geometric series by using a formula follow all the steps given below.

Here,

If a, b, c, d, e ............ are in geometric progression.

Then,

The series is geometric.

Then,

Therefore, The series is geometric.

Then,

Therefore, The series is geometric.

Then,

Therefore, The series is geometric.

Then,

Therefore, The series is not geometric.

Then,

Therefore, The series is geometric.

Then,

Therefore, The series not is geometric.

Step-by-step explanation:

john has 55 candy left.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
