What is the common ratio of the geometric sequence below?
… 625, 125, 25, 5, 1, ... A. This is a problem our NEVER went over. To determine the common ratio of a geometric sequence, you may need to solve an equation of this form: r 4 =81 then r 2 =9 and r=3 or r=-3. Add comment More. 25/125 C. 625/125 D. 125/5 2 See answers Answer 4.6 /5 49. -3 c. -12 d. 9 Answer by MathLover1(17219) (Show Source): You can put this solution on YOUR website! The values of a, r and n are: a = 10 (the first term) r = 3 (the "common ratio") n = 4 (we want to sum the first 4 terms) So: Becomes: You can check it yourself: 10 + 30 + 90 + 270 = 400. 25/125 C. 625/125 D. 125/5 2 See answers Answer 4.6 /5 49.

Geometric Sequences. r = 4 2 = 2 2 is the common ratio. Given the geometric sequence 2 , 4 , 8 , 16 ... To find the common ratio , find the ratio between a term and the term preceding it.
Follow • 3. 1/625 B. 2020 Find the common ratio of the geometric sequence 36, 6, 1, 16.... Write your answer as an integer or fraction in simplest form? is geometric, because each step divides by 3. Find the common ratio of the geometric sequence. So we'll work from 1 to 5, 5 to 25, 25 to 125, and so on. A geometric sequence is one in which any term divided by the previous term is a constant. Sequence E has common ratio -1.5. To find the common ratio, divide the 2nd term by the 1st term (3/10) / (3/4) = 3/10 * 4/3 = 12/30 = 2/5 <== In a geometric sequence, the next term is found by multiplying the term by the common ratio. In a Geometric Sequence each term is found by multiplying the previous term by a constant.

This sequence has a factor of 3 between each number. Each term of a geometric sequence increases or decreases by a constant factor called the common ratio.The sequence below is an example of a geometric sequence because each term increases by a constant factor of 6. The common ratio can be found by dividing any term in the sequence by the previous term.
