An aritmetic sequcne is represented as
![a_n=a_1+d(n-1)](https://tex.z-dn.net/?f=a_n%3Da_1%2Bd%28n-1%29)
where
an=nth term
a1=first term
d=common differnce, or how much each term increases by
n=which term
example
1,3,5, etc
first term is 1
common difference is 2 because it increases by 2 each time
so the formula would be
![a_n=1+2(n-1)](https://tex.z-dn.net/?f=a_n%3D1%2B2%28n-1%29)
if we had
5,3,1
first term s 5
common difference is -2 since it goes up by -2 each time
so formula is
![a_n=5-2(n-1)](https://tex.z-dn.net/?f=a_n%3D5-2%28n-1%29)
hope this helps
Answer:
42%
Step-by-step explanation:
So the total amount of birds spotted are 140.
The amount of Blue Jays spotted is 59.
take 59/140
59/140 = 0.42
0.42 x 100 = 42
42% is the probability that papa sees a Blue Jay.
Nevermind my question above, it was stupid.
The perimeter is 100 ft. because there are 4 sides and two are 20 feet long and the other 2 are 40 feet long (40, because the length is twice as long as the width, which is 20), and <span>20+20+40+40=100.</span>
