EXPLANATION
The nth term of the sequence is given by
Where
is the first term and
is the constant difference.
We were given that,
S we just need the common difference to write the nth term.
We can get that from another information given to us.
We were also given that the 4th term is 6. This gives the equation.
We substitute
to obtain
Or
This implies,
We substitute these values into the general formula to obtain,
This gives us,
Hence the nth term of the sequence is,
One minute is 60 seconds. I'm using this equation: Vf= Vi+at
40/60=2/3=0.666...m/s^2
Answer:
Is this all of the question?
Step-by-step explanation:
In this equation, you are solving for y. Simply isolate the variable by adding 1/4 to each side. The -1/4 and 1/4 will cancel out on the right side of the equation, leaving only y:
5/4 = y - 1/4
5/4 + 1/4 = y - 1/4 + 1/4
6/4 = y
y = 6/4
Don't forget to simplify y:
y = 3/2
