Salutations!
finding the 56th term is same as find the nth term, but its a bit more easier than finding the nth term.
we'll be using a formula to find the fifth term.
![a+(n-1)*d](https://tex.z-dn.net/?f=a%2B%28n-1%29%2Ad)
![a](https://tex.z-dn.net/?f=a)
stands for the first term (the first number in a sequence)
![d](https://tex.z-dn.net/?f=d)
is the difference between the constants
![n](https://tex.z-dn.net/?f=n)
is the what will be finding
so instead of n, we will be plugging in the number 56.
![a+(n-1)*d](https://tex.z-dn.net/?f=a%2B%28n-1%29%2Ad)
![23+(56-1)*-7](https://tex.z-dn.net/?f=23%2B%2856-1%29%2A-7)
we will be solving the brackets first
![23+55*-7](https://tex.z-dn.net/?f=23%2B55%2A-7)
![78-7](https://tex.z-dn.net/?f=78-7)
=71
the 56th term is 71
hope this helps!
have a great day!
Answer:
4.24sq. in.
Step-by-step explanation:
I actually got 4.72 sq. in. but that's the closest answer so *shrug*
A= πr^2
then divide that by 6
You need to work out the width
Answer:
X is 2 bcz 3+5 is 8 then 8/4 is 2
