Answer:
x=0
Step-by-step explanation:
-3 -1
---------- = -----------
x+3 x+1
We can solve using cross products
-3 *(x+1) = -1(x+3)
-3x -3 = -1x -3
Add 3x to each side
-3x -3 +3x = -x -3 +3x
-3 = 2x -3
Add 3 to each side
-3+3 = 2x-3+3
0 =2x
Divide by 2
0/2 =2x/2
0=x

Answer:
Step-by-step explanation:
The recursive formula given is:
Generally a recursive formula is given as:
where a = first term
d = common difference
This implies that:
a = 5
d = -4
A general formula for an arithmetic sequence is:
Therefore, the general formula for the sequence is:
