The later academics question and answer requested students to claim what they presume is the most important point for a student to do if they wanted to gain success. One which response stood out from the rest was practice. Successful persons ordinarily are not born successful; they become successful thru hard work and determination. If you tend to attain your goals, keep this in mind! right below are one of the answer and question example that you can potentially implement to practice and improve your understanding and also give you insights that might help you to sustain your study in school.

## Question:

Which sequences are geometric? Check all that apply. –2, –4, –6, –8, –10, … 16, –8, 4, –2, 1 –15, –18, –21.6, –25.92, –31.104, … 4, 10.5, 17, 23.5, 30, … 625, 125, 25, 5, 1, …

The sequences which are geometric are;

• –8, 4, –2, 1
• -15, –18, –21.6, –25.92, –31.104
• 625, 125, 25, 5, 1,

A sequence is geometric if successive terms of the sequence differ by a given factor r.

In the question;

Geometric Sequence:

• –8, 4, –2, 1. has a common ratio,r = (-1/2)
• -15, –18, –21.6, –25.92, –31.104 has a common ratio, r = (1.2)
• 625, 125, 25, 5, 1 has a common ratio, r= (1/5)
