Tx power difference question

In general, what is the difference in transmit power between an AP operating at Tx Power Level 1 and the same AP operating at Tx Power Level 3?

6dB is the correct answer but can someone explain why it is right answer

My only guess is because of table 8-3 in this document: Channels and Maximum Power Settings for Cisco Aironet Lightweight Access Points, OL-11321-07 - Cisco Aironet 1300 Series Access Point/Bridge [Cisco Aironet 1240 AG Series] - Cisco Systems

Power level 3 is approximately one quarter power of level 1. Because the power is halved 2 times or doubled 2 times there is a 6 db difference.
