Answer:
Step-by-step explanation:
The nth term of the given arithmetic sequence is
The first term of this series is:
The last term of this series is when
The sum of the first n terms of an arithmetic series when the first an last term is known is given by:
Where a=5 is the first term and l=27 is the last term.
The slope is 3/1, so it simplifies to 3

z=3. If z varies inversely as w, and z=4 when w=9, then when w=12 the value of z is 3.
The key to solve this problem is using reverse proportionality, in which two magnitudes a and b are inversely proportional when there is a constant k such that
a⋅b=k, where constant k is called the proportionality constant.
Then if z varies inversely as w, and z=4 when w=9
z.w=k -------> 4.9=k -------> k=36
So, let's find z when w = 12. With k = 36
z.w=K, clear z from the equation
z=k/w -------> z=36/12 -----> z=3
