Answer:
a_n = 2.2 + 0.6 n
a_50 = 32.2
Step-by-step explanation:
What's the common difference of this series?
![a_1 = 2.8](https://tex.z-dn.net/?f=a_1%20%3D%202.8)
![a_2 = 3.4](https://tex.z-dn.net/?f=a_2%20%3D%203.4)
Common difference =
.
Expression for the nth term:
![a_n = a_1 + (n - 1) \cdot\text{Common Difference} \\\phantom{a_n } = 2.8 + 0.6 \; (n-1) \\\phantom{a_n} = 2.8 + 0.6 \; n - 0.6\\\phantom{a_n} = 2.2 + 0.6\; n](https://tex.z-dn.net/?f=a_n%20%3D%20a_1%20%2B%20%28n%20-%201%29%20%5Ccdot%5Ctext%7BCommon%20Difference%7D%20%5C%5C%5Cphantom%7Ba_n%20%7D%20%3D%202.8%20%2B%200.6%20%5C%3B%20%28n-1%29%20%5C%5C%5Cphantom%7Ba_n%7D%20%3D%202.8%20%2B%200.6%20%5C%3B%20n%20-%200.6%5C%5C%5Cphantom%7Ba_n%7D%20%3D%202.2%20%2B%200.6%5C%3B%20n)
n = 50 for the fiftieth term. Therefore
