Answer:
![T_n= 9+(n-1)](https://tex.z-dn.net/?f=T_n%3D%209%2B%28n-1%29)
Step-by-step explanation:
The Given sequence is 9, 10, 11, 12
We need to find the expression to describe the sequence.
Let
be the
term of the sequence.
Let n represent the position of the term.
Let a be the first term in the sequence.
and d be the common difference between the sequence
Hence the expression to find the above sequence is given below;
![T_n= a+(n-1)d](https://tex.z-dn.net/?f=T_n%3D%20a%2B%28n-1%29d)
when n=1 d= 1 a = 9
![T_1 = 9+(1-1)1 = 9 + 0 = 9](https://tex.z-dn.net/?f=T_1%20%3D%209%2B%281-1%291%20%3D%209%20%2B%200%20%3D%209)
when n=2 d= 1 a = 9
![T_2 = 9+(2-1)1 = 9 + 1 = 10](https://tex.z-dn.net/?f=T_2%20%3D%209%2B%282-1%291%20%3D%209%20%2B%201%20%3D%2010)
when n=3 d= 1 a = 9
![T_3 = 9+(3-1)1 = 9 + 2 = 11](https://tex.z-dn.net/?f=T_3%20%3D%209%2B%283-1%291%20%3D%209%20%2B%202%20%3D%2011)
when n=3 d= 1 a = 9
![T_4 = 9+(4-1)1 = 9 + 3 = 12](https://tex.z-dn.net/?f=T_4%20%3D%209%2B%284-1%291%20%3D%209%20%2B%203%20%3D%2012)
Hence the expression is ![T_n= 9+(n-1)](https://tex.z-dn.net/?f=T_n%3D%209%2B%28n-1%29)
