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
Answer:
Distributive
Step-by-step explanation:
You distribute the 5 into 3x+18, multiplying it by each part of the equation (each part is separated by one of these signs: +, -, x, or /) to get 15x (from 5 x 3x) plus 60 (from 5 x 18).
Answer: Answers and work are all in the picture that I attached. Hope this helps
12*-9 is simply 12 * 9 with a negative at the end. I use a strategy as I'm in 8th grade that I learned in 5th this should help. If you love to hat that is bad. this is for division and multiplication this is stating that if a positive( love ) number times or divided by a negative( hate ) number it is negative( bad ). so 12*9=108 and add the negative and your answer is -108
Hope this helps:) good luck!
Answer:
well it looks equal to 15 cm so its probably 15 cm
