The arithmetic sequence is an=a1+(n-1)d.
For number 1 it would be an=6+5n-5 or an=5n+1.
For number 2, the next two terms would be 28 and 33.
Hope this helps you!
You would have to use this equation : y2-y1/x2-x1 = slope
So it would be -13 +3/6-2= -10/4
Simplify it and you get : -5/2
Slope is -5/2
Step-by-step explanation:
Geometric Sequence formula for general term:
an = a1(r^n-1)
a1 = 4 × (-5)^1-1
a1 = 4
r = -5
Summation formula for geometric sequence :
Sn = a1 ( 1 - r^n / 1 - r )
...<em>take n from the top of the summation.</em>
= 4 ( 1 -(-5)^6 / 1 -(-5)
= -10416.
Use the equation 2πr (so it would be 2π5 or 31.4)
