    Mean: Mean Is You add all and you divide then by how many numbers you have Like 21+42+63+84+105+126+147=504

    504:7=72

    Medium: Is the Middle Number of the Set

    So whats the Middle number of the set?

    21, 42, 63, 84, 105, 126, 147

    84 Is in the Middle of the set

    Mode: is when the Number is Repeated different times in the set

    But in this set we don't have Multiple of the the same Number so heres an Example

    13, 13, 13, 13, 14, 14, 16, 18, 21

    So you see 13 Is the Most common Number for so 13 is the Mode.
