Answer:
![T_n = 3+ 4n](https://tex.z-dn.net/?f=T_n%20%3D%203%2B%204n)
Step-by-step explanation:
From the question, we understand that:
---- First Term
---- Common difference
Required
Determine the nth term
nth term of a sequence is calculated using:
![T_n = T_1 + (n - 1)d](https://tex.z-dn.net/?f=T_n%20%3D%20T_1%20%2B%20%28n%20-%201%29d)
Substitute values for
and ![d](https://tex.z-dn.net/?f=d)
![T_n = 7 + (n - 1) * 4](https://tex.z-dn.net/?f=T_n%20%3D%207%20%2B%20%28n%20-%201%29%20%2A%204)
Open bracket
![T_n = 7 + 4n - 4](https://tex.z-dn.net/?f=T_n%20%3D%207%20%2B%204n%20-%204)
Collect Like Terms:
![T_n = 7 - 4+ 4n](https://tex.z-dn.net/?f=T_n%20%3D%207%20-%204%2B%204n)
![T_n = 3+ 4n](https://tex.z-dn.net/?f=T_n%20%3D%203%2B%204n)
Hence, the nth term of the sequence is:
![T_n = 3+ 4n](https://tex.z-dn.net/?f=T_n%20%3D%203%2B%204n)
Answer:
depends
Step-by-step explanation:
Answer:
C. 4(3x+2)
Step-by-step explanation:
Each side of a square is equal to each other, so the perimeter would be 4*(3x+2).
Answer:
ACB=90-62
ACB=28
Therefore we say CAB is 28.
