Let x to be the first term (number) in five consecutive even numbers.
First number = x
Second number = x+%2B+2
Third number = x+%2B+4
Fourth number = x+%2B+6
Fifth number = x+%2B+8
Mean=Sum+Of+Numbers%2FNumber+Of+Terms+Of+The+Numbers
16=%28x%2B%28x%2B2%29%2B%28x+%2B+4%29%2B%28x+%2B+6%29%2B%28x+%2B+8%29%29%2F5
16=%285x%2B20%29%2F5
80=5x%2B20
60=5x
60%2F5=x
12=x
x=12
First number = x = 12 (which is the least number in five consecutive even numbers)

Let say the question is modified and become "If the mean of five consecutive odd numbers be 16, what is the least number?"
Let x to be the first term (number) in five consecutive odd numbers.
First number = x+%2B+1
Second number = x+%2B+3
Third number = x+%2B+5
Fourth number = x+%2B+7
Fifth number = x+%2B+9
Mean=Sum+Of+Numbers%2FNumber+Of+Terms+Of+The+Numbers
16=%28%28x+%2B+1%29%2B%28x%2B3%29%2B%28x+%2B+5%29%2B%28x+%2B+7%29%2B%28x+%2B+9%29%29%2F5
16=%285x%2B25%29%2F5
80=5x%2B25
55=5x
55%2F5=x
11=x
x=11
First number = x = 11 (which is the least number in five consecutive odd numbers)
