Question

Find the mean of first 12 even natural numbers.​

Answer 1

Answer:

Mean of first 12 even natural numbers = 13

Step-by-step explanation:

Mean

= Sum of all observations/ Number of observations

Sum of all observations

= Sum of first 12 even natural numbers

= 2+4+6+8+10+12+14+16+18+20+22+24

= 156

Total number of observations= 12

Mean = 156/12 = 13

Answer 2

As we know,

mean =sum of all terms /no. of all the terms

mean=2+4+6+8+10+12+14+16+18+20+22+24/12

=156/12=13

So the mean of first 12 even natural numbers is 13
