Answer:
- -1/3
- not geometric
- -5
- 4
Step-by-step explanation:
You find the ratio of terms by dividing the second by the first. If the ratio is the same for all adjacent pairs of terms, it is a "common" ratio.
1) (2/3)/-2 = -1/3
(-2/9)/(2/3) = -1/3
(2/27)/(-2/9) = -1/3 . . . . . the common ratio is -1/3
___
2) 2/0 = undefined . . . . not a geometric sequence
___
3) -10/2 = -5
50/-10 = -5
-250/50 = -5 . . . . . the common ratio is -5
___
4) 4/1 = 4
16/4 = 4
64/16 = 4 . . . . . the common ratio is 4
Answer:
~ 7m-20
Explanation:
~ First, we need to look at like terms and collect them. Like terms are similar numbers like all the m’s can be collected together.
~ Let’s count the number of m’s first. M+m+m+2m+2m should give you 7m.
~ Now lets just count the rest of the numbers: 15+15-30-20. 15+15=30, 30-30=0 and 0-20=-20.
~ Hence you get the answer of 7m-20
