Step #2: Calculate the average and mean of data set by adding all the numbers and dividing the total by the number of items in data set. (3 + 7 + 7 + 19) / 4 = 9 vs (2 + 5 + 6 + 7) / 4 = 5
WebProve that the sum of two consecutive integers is always odd. And integer is a whole numberLet the integer = 2X meaning it is even and the next number is (2X+1) making it oddTherefore the sum of the two consecutive integers is2X + 2X + 1=4X+1As this cannot be factorised by 2 provibg this has proved it is odd.
