Answer:
3,888
Step by step explanation:
Just multiply by 3 to get the next number
or
Nth term= 16 x (3^N-1)
It would be 1/5 because the line is going in a positive direction and all you have to do is pick to points and do rise/run
X = 4/15 or 0.26
First add the numbers on the left side of the equation.
0.72 = 0.8 - 0.3x
Then move the variable to the left as well.
0.3x + 0.72 = 0.8
Move the constant to the right by subtracting.
0.3x = 0.8 - 0.72
Subtract the numbers
0.3x = 0.08
Divide both sides by 0.3.
And that should yield your answer.
Hope this helps. ^^
