Answer: First Option  is correct.

Step-by-step explanation:

Since we have given that

\sum_{n=1}^{n=\infty}(3+an)

Here, a = 3

So, our sequence becomes,

3+a,3+2a,3+3a,................

So, we can see that there is a common difference i.e. 'd'.

d=a_2-a_1=3+2a-(3+a)=3+2a-3-a=a

So, it becomes an arithmetic progression.

Hence, First Option is correct.

Elvira’s cafeteria has cartons of milk that are typical of school lunch. The milk supplier charges $0.35 per carton of milk, in
FromTheMoon [43]
Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.
