Vrms is  the (square)Root of the Mean of the Squares (of the Voltage
samples). When  you work out Vrms^2 in order to work out the power, you are
squaring the  squareroot, so the r in rms disappears and you are left with
the Mean of  the Squares (of the Voltage samples) --- (V^2)mean or
(V^2)average, if you  prefer. (V^2)average/R = Paverage.

Steve,
 
 This is an explanation that makes sense and one that I can  understand.
 
Thanks,
 
Dennis O.
