## anonymous one year ago ill medal & fan Which of the following best describes the common ratio in the sequence 6310, 1577.5, 394.375, 98.59375, ...? 6306 8 1/4 4

1. Nnesha

ratio between two numbers in a geometric sequence number are in the sequence are increasing or decreasing by same number to find common ration you can divide next term by the previous one hmm like this $\rm r=\frac{ a_2 }{ a_1} ~~or~~\frac{ a_3 }{ a_2 }$

2. Nnesha

ratio *

3. Nnesha

a_2 means 2nd term a_1 = first term a_3 = 3rd term

4. Nnesha

make sense ?
