Insert three arithmetic means between 11 and 35

To insert three arithmetic means between 11 and 35, we need to find a sequence with five terms where 11 is the first term, 35 is the fifth term, and the three arithmetic means are the second, third, and fourth terms. 

Let's denote the sequence as \( a_1, a_2, a_3, a_4, a_5 \), where:

- \( a_1 = 11 \)
- \( a_5 = 35 \)

The common difference \( d \) between consecutive terms in an arithmetic sequence can be found using the formula:

\[
d = \frac{a_5 - a_1}{4}
\]

Substituting the values:

\[
d = \frac{35 - 11}{4} = \frac{24}{4} = 6
\]

Now we can find the three arithmetic means:

1. **Second term ( \( a_2 \) ):**
   \[
   a_2 = a_1 + d = 11 + 6 = 17
   \]

2. **Third term ( \( a_3 \) ):**
   \[
   a_3 = a_2 + d = 17 + 6 = 23
   \]

3. **Fourth term ( \( a_4 \) ):**
   \[
   a_4 = a_3 + d = 23 + 6 = 29
   \]

So, the three arithmetic means between 11 and 35 are **17, 23,** and **29**.
