Question

Find the arithmetic mean for the first 8 whole numbers.​

Answer 1

Answer:

Step-by-step explanation:

The first 8 natural numbers are 1, 2, 3, 4, 5, 6, 7 and 8. Now, their summation will be given as 1+2+3+4+5+6+7+8=36. ... Thus, on dividing the summation value by 8 we get, 368=4.5. Thus, the mean of the first 8 natural numbers will be 4.5.

Answer 2

$\boxed{\large \boxed{ \boxed{ \underline{ \underline{\sf{ᴀɴsᴡᴇʀ: }} }}}}$

$\sf{first \: eight \: whole \: numbers \: are \: : - } \\ \sf{0, \: 1, \:2 , \: 3, \: 4, \: 5, \: 6, \: 7}$

$\sf{mean = \frac{sum \: of \: observations}{number \: of \: observations} } \\ \\ \sf{mean = \frac{0 + 1 + 2 + 3 + 4 + 5 + 6 + 7}{8} } \\ \\ \sf{mean = \frac{28}{8} } \\ \\ \boxed{\sf{mean = 3.5}}$
