First 10 Natural numbers are:- 1,2,3,4,5,6,7,8,9,10
Mean = Sum of all numbers/ total number of observations
= 1+2+3+4+5+6+7+8+9+10 / 10
= 55/ 10
= 5.5
Therefore, 5.5 is the mean of first 10 natural numbers

in this question mean is already given and we know that:-
mean = sum of total numbers / total number of observations
15 = 2+6+7+a / 4
15*4 = 15+a
60 = 15+a
60-15 = a
a= 45
now we have found the value of a=45, we will put this value in second series:-
mean = sum of all numbers / total number of observations
50 = 6+18+1+45(value of a) + b / 5
50*5 = 70 + b
250 = 70 + b
b = 250 - 70
b = 180
