Find thearithmetic mean of the first 7 natural numbers Select one a. 8 b. 1 C. 12. d. 4 ​

Answer 1

Answer:

Mean = 4

Step-by-step explanation:

Mean of First 7 natural numbers.

1, 2, 3, 4, 5, 6, 7

Sum of terms = 1+2+3+4+5+6+7 =28

No. of terms = 7

Mean = Sum of terms / No. of terms

= 28/7 = 4

Answer 2

Hey there,

first 7 natural numbers = 1,2,3,4,5,6,7

now,

we know arithmetic mean = n+1 /2

arithmetic mean of first 7 natural numbers

= n + 1 /2

putting n = 7, we get -

= 7 + 1 /2

= 8 /2

= 4

Therefore answer is (option d.) 4
