- Let's define the numbers: Let the second number be \( x \).

- The first number is 5 times the second number, so it's \( 5x \).

- The difference between the first and second numbers is 120, i.e., \( 5x - x = 120 \).

- Solve for \( x \): \( 4x = 120 \), so \( x = 30 \).

- Therefore, the first number is \( 5 \times 30 = 150 \).

- Find the average of the two numbers: \( \frac{30 + 150}{2} = 90 \).

- Evaluate options:

- Option 1: 90

- Option 2: 80

- Option 3: 95

- Option 4: 85

The correct answer is Option 1: 90.
