Question

Determine if the sequence is arithimetic if it is find the common difference , the explicit formula , and the recursive formula
1. 0,9,18, 2
A. Common difference : d=10
Explicit :=-10+10n
Recursive : an=an-1+10
a1=0
B. Common Difference : d=7
Explicit : an=-8+7n
Recursive : an=an-1+7
a1=-1
C. Common difference : d=7
Explicit: an=-7+7n
Recursive : an=an-1+7
a1=0
D . Common difference : d=9
Explicit : an=-9+9n
Recursive : an=an-1+9
a1=0
