What is an expression for the nth term of the following sequence 4 1 -2 -5 -8

4 - (n-1) x 3

Test

4 - (2nd term - 1 x 3 = 3) so 4-3=1 which is the second term

4 - (3rd term - 1 = 2 x 3 = 6) 4-6=-2 which is the sequence

Step-by-step explanation:

For every term 3 is subtracted so you can multiply as a shortcut.

You subtract because of the first term not being subtracted.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

true
