Is the answer 20?
That's how I got the answer.
The sequence number is already arranged in ascending order. So what I did is Separate the sequence number into 2 part.
First part is the first 5 digits while the second part is the last 5 digits. Then, choose the middle number in each of the 5 digits. Use the larger number to minus the smaller number.

To find the distance between two coordinates on a graph, use the Distance Formula: D = √((x₁ - x₂)² + (y₁ - y₂)²).

Our values for x₁, x₂, y₁, and y₂ will be replaced with the x- and y-values in the given coordinates, (5, 6) and (-4, -7).

Substitute.

√((x₁ - x₂)² + (y₁ - y₂)²)

√((-4 - 5)² + (-7 - 6)²)

Subtract.

√(-9² + (-13)²)

Square.

√(81 + 169)

Add.

√(250)

Simplify.

√(5² · 5 · 2)

√(5²)√(2 · 5)

5√(10) or approx 15.8114

Answer:

B. 15.81 units
