To find the 61st term of the given arithmetic sequence, we first need to establish the key components of the sequence:

### Sequence:
\[ 3, 10, 17, 24, \dots \]

### Step 1: Determine the Common Difference (\(d\))
The common difference \(d\) in an arithmetic sequence is found by subtracting the first term from the second term:
\[
d = 10 - 3 = 7
\]

### Step 2: Use the Formula for the \(n\)-th Term of an Arithmetic Sequence
The formula to find the \(n\)-th term of an arithmetic sequence is:
\[
a_n = a_1 + (n - 1) \cdot d
\]
where:
- \(a_n\) is the \(n\)-th term,
- \(a_1\) is the first term,
- \(d\) is the common difference,
- \(n\) is the term number.

### Step 3: Plug in the Values to Find the 61st Term
Here, we need to find the 61st term (\(n = 61\)). The first term \(a_1 = 3\), and the common difference \(d = 7\). Using the formula:
\[
a_{61} = 3 + (61 - 1) \cdot 7
\]
\[
a_{61} = 3 + 60 \cdot 7
\]
\[
a_{61} = 3 + 420 = 423
\]

### Final Answer:
The 61st term of the arithmetic sequence is **423**.
