    92

    Step-by-step explanation:

    one easy way to do it is to break down the process of averaging numbers. 90*3 = the two nums you have + unknown

    the equation you write can be like

    90 = (82+96 + incog) / 3

    90*3 = (82+96 + incog)

    270=178 + incog

    270-178 = incog

    incog=92
