What is the average of all integers between 200 and 350 that are exactly divisible by 11?

Question

Accepted Answer

1. Smallest multiple of 11 ≥ 200: $19	imes11=209$.
2. Largest multiple of 11 ≤ 350: $31	imes11=341$.
3. These form an arithmetic progression, so average = $\frac{	ext{first}+	ext{last}}{2}$.
4. Average = $\frac{209+341}{2}=275$.
