Given that
![a_1=24](https://tex.z-dn.net/?f=a_1%3D24)
and
![a_2=17](https://tex.z-dn.net/?f=a_2%3D17)
, if
![a_n](https://tex.z-dn.net/?f=a_n)
is an arithmetic sequence, then the common difference between successive terms is
![d=a_2-a_1=17-24=-7](https://tex.z-dn.net/?f=d%3Da_2-a_1%3D17-24%3D-7)
.
You then have
![a_2=a_1+d](https://tex.z-dn.net/?f=a_2%3Da_1%2Bd)
![\implies a_3=a_2+d=a_1+2d](https://tex.z-dn.net/?f=%5Cimplies%20a_3%3Da_2%2Bd%3Da_1%2B2d)
![\implies a_4=a_3+d=a_1+3d](https://tex.z-dn.net/?f=%5Cimplies%20a_4%3Da_3%2Bd%3Da_1%2B3d)
![\implies \cdots\implies a_n=a_{n-1}+d=\cdots=a_1+(n-1)d](https://tex.z-dn.net/?f=%5Cimplies%20%5Ccdots%5Cimplies%20a_n%3Da_%7Bn-1%7D%2Bd%3D%5Ccdots%3Da_1%2B%28n-1%29d)
So the explicit formula for the
![n](https://tex.z-dn.net/?f=n)
th term is
If 16.1cm is a radius of circle:
# Area= Pi X R{2}
= 3.141592654 X 16.1 square
= 814.3 cm square
# circumference= Pi X 2 X R
= 3.141592654 X 2 X 16.1
= 101.2 cm
# if 16.1 is a diameter:
#Area= Pi X D/2 square
= 3.141592654 X 16.1 divide by 2 square
= 203.6 cm square
#Circumference= Pi X D
= 3.141592654 X 16.1
=50.6 cm
That's it it. a bit long cuz I dun know what exactly what they given Radius or Diametre.
