Answer:
First 12 natural numbers are: 1,2,3,4,5,6…. ... Now, substitute 78 for the sum of observations and 12 for the total number of observations in the formula M=Sn to determine the arithmetic mean. M=Sn=7812=6.5. Hence, 6.5 is the arithmetic mean of the first 12 natural numbers.

Answer:
13/2
Step-by-step explanation:
natural number are = 1,2,3,4,5,6...
1st 12 natural no are = 1,2,3,4, 5, 6,7,8,9,10,11,12
Mean = sum of all no / by total no
Mean = 1+2+3+4+5+6+7+8+9+10+11+12/12
Mean = 78/12
Mean = 13/2
