Answer:
Common Difference: 
The ninth term: -1
Step-by-step explanation:
The sequence can be written like this,
3, 2.5, 2, 1.5, 1, ....
Here the common difference is clearly -0.5 or , and we can conclude that 
number is 
. So the 9th term is,
<span>20.2 =0 tens + 202 tenths.
20.2= 10 tens + 102 tenths</span>
1. Four hundred thousand thirty two and ten point one
2. Standard form is adding it out ( 945.35 ) = 900 + 40 + 5 + .30 + .05
3. Expanded form ( 73,890 )
| ten thousands | thousands | hundred | tens | ones | decimal | tenths | hundredths |
7 3 8 9 0 . 0 1
1m=100cm,
so 25 m=25*100=2500cm
