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, …

Answer:

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)

From the answer and question examples above, hopefully, they can help the student deal with the question they had been looking for and keep in mind of every piece stated in the answer above. Then could certainly have some sharing in a group discussion and also study with the classmate about the topic, so another student also attain some enlightenment and still keeps up the school learning.
