To find the three consecutive odd integers such that the sum of the first, two times the second, and three times the third is 70, let's define the integers and set up the equation.

Let the three consecutive odd integers be:
- \( x \) (the first odd integer)
- \( x + 2 \) (the second odd integer)
- \( x + 4 \) (the third odd integer)

According to the problem, the sum of the first, two times the second, and three times the third is 70. This gives us the equation:
\[ x + 2(x + 2) + 3(x + 4) = 70 \]

Now, let's solve this equation step by step:

1. Expand the equation:
\[ x + 2x + 4 + 3x + 12 = 70 \]

2. Combine like terms:
\[ x + 2x + 3x + 4 + 12 = 70 \]
\[ 6x + 16 = 70 \]

3. Subtract 16 from both sides:
\[ 6x = 54 \]

4. Divide both sides by 6:
\[ x = 9 \]

So, the first odd integer is 9. Therefore, the three consecutive odd integers are:
- \( x = 9 \)
- \( x + 2 = 11 \)
- \( x + 4 = 13 \)

Let's verify the solution:
- First integer: \( 9 \)
- Second integer: \( 11 \)
- Third integer: \( 13 \)
- Sum: \( 9 + 2 \cdot 11 + 3 \cdot 13 = 9 + 22 + 39 = 70 \)

The solution is correct. The three consecutive odd integers are 9, 11, and 13.
