To find the common and to see whether the sequence is geometric or not you have to divide n+1 term to n term.

For example 2nd to 1st:
6:2=3
18:6=3

The answer is yes. The sequence is geometric and the common ration is 3. I hope that this is the answer that you were looking for and it has helped you.

7r-5r+8=9r+8-r translate to an equation, then solve

pshichka [43]

Answer:

r=0

Step-by-step explanation:

7r-5r+8=9r+8-r

This is already an equation

Combine like terms

2r+8 = 8r+8

Subtract 2r from each side

2r-2r +8 = 8r-2r +8

8 =6r+8

Subtract 8 from each side

8-8 = 6r+8-8

0 = 6r

Divide by 6

0/6 = 6r/6

0 =r
