Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
Because without place value you might put the decimal in the wrong place and that will effect the answer big time.
4x-3=5y
it would be : 4x - 5y = 3
