1. Muammo: Berilgan sonlar qatorining orasidagi farqni topish: $2 \frac{1}{3}$, $5 \frac{1}{4}$, $\frac{5}{7}$, $5 \frac{6}{7}$.\n\n2. Aralash kasrlarni oddiy kasrlarga aylantiramiz:\n$2 \frac{1}{3} = \frac{7}{3}$,\n$5 \frac{1}{4} = \frac{21}{4}$,\n$\frac{5}{7}$ o'zgarmaydi,\n$5 \frac{6}{7} = \frac{41}{7}$.\n\n3. Oraliq farqni topish uchun ketma-ket sonlar orasidagi farqni hisoblaymiz:\n$a_2 - a_1 = \frac{21}{4} - \frac{7}{3} = \frac{63}{12} - \frac{28}{12} = \frac{35}{12}$,\n$a_3 - a_2 = \frac{5}{7} - \frac{21}{4} = \frac{20}{28} - \frac{147}{28} = -\frac{127}{28}$,\n$a_4 - a_3 = \frac{41}{7} - \frac{5}{7} = \frac{36}{7}$.\n\n4. Natija: Sonlar qatorining orasidagi farqlar ketma-ket $\frac{35}{12}$, $-\frac{127}{28}$ va $\frac{36}{7}$ ga teng.
