Yechim qadamlari

1,2,3,4,5,6,7,8,9,10 to‘plamining o‘rtachasini topish uchun avval a‘zolarni birgalikda qo‘shing.

$$1+2+3+4+5+6+7+8+9+10=55$$

1,2,3,4,5,6,7,8,9,10 to‘plamining o‘rtachasi a‘zolarining yig‘indisini a‘zolari soniga bo‘lish bilan aniqlangan va bu holatda 10.

$$\frac{55}{10}=\frac{11}{2}$$

Omil

$$\frac{11}{2} = 5\frac{1}{2} = 5,5$$
