8600

8640

360

- Let's examine the number series: 12, 72, 360, 1440, 4320, 8640, 8600.

- Each number appears to be the result of a multiplication pattern.

- Observe that 12 x 6 = 72.

- Then, 72 x 5 = 360.

- Next, 360 x 4 = 1440.

- After that, 1440 x 3 = 4320.

- Continuing, 4320 x 2 = 8640.

- Finally, applying the pattern, 8640 x 1 should equal 8640, but we have 8600, which doesn't fit.

- Therefore, the wrong number appears to be in place of the last term, as "8600" should actually be "8640."
