| The scene shows a sequence of numbers arranged horizontally from left to right. Each number is displayed as a digit in the center of the frame. The last position contains a question mark (?) indicating the missing number. Observe the arithmetic pattern: each number differs from the previous one by a constant value (the common difference). Calculate the difference between consecutive visible numbers to identify the step size. Apply this step size to the last visible number to determine the missing value. Replace the question mark with the correct number that completes the arithmetic sequence. |
