Answer:
a screw is a simple machine that works as a modified inclined plane. You can think of the thread of the screw as an inclined plane wrapped around the shaft of the screw. The slope of the screw is the distance for one complete rotation while the height of the inclined plane is the distance between the threads, known as pitch. The relationship between the pitch and circumference of the screw gives the mechanical advantage.

so each term is ound by subtracting 13 from the previous term
an aritmetic sequence can be written as
were
is the nth term
is the first term
d is common difference, which can also be found by doing 
n=wich term
we know that
and we can find d
, 
so te general term is
which can also be expanded and written as 
Answer:
The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
