Question

mean of first 5 multiples of 2

Answer 1

answer will be
(2+10)/2=6

Answer 2

first 5 multiples of 2 = 2 , 4 , 6 , 8 , 10



their sum = 2( 1 + 2 + 3 + 4 + 5 )
their sum = 2( 15 )
their sum = 30 --------:( 1 )




We know ,Mean = ( sum of observations ) ÷ ( number of observations )





Hence,

Mean = ( sum of first 5 multiples of 2 ) / 5






putting value from ( 1 )

mean = 30 / 5

mean = 6
