Question

calculate mean of first 20 natural numbers​

Answer 1

Answer:

Natural numbers are positive whole numbers.

The first 20 natural numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20.

Use the formula Average = Sum of Values ÷ Number of Values to find the answer.

(1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20) ÷ 20

= 210 ÷ 20

= 10.5

Hence, the average of the first 20 natural numbers is 10.5.

Answer 2

Answer:

10.5

Step-by-step explanation:

Mean is the sum of the observations divided by mean of the observations => 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20/20

=>210/20 = 10.5
