121 in base 4 = 16 + 8 + 1 (base ten) = 25
84 in base 16 = 128 + 4 (base ten) = 132132 + 25 = 157(base 10) = 9D (base 16) = 2131 (base 4)
26 plus 16 plus 84 is equal to 126.
4(21 + 4)
84 + 16 = 100
That sum is 84. Since it's only one number, its mean is also 84. If those numbers were simply listed, without being added, then their mean would be 16.8 .
