Keling, berilgan formulani ko'rib chiqamiz: \( a_n = -2(1-n) \). Agar ketma-ketlik arifmetik progressiya bo'lsa, unda har ikki qo'shni a'zolarining farqi doimiy bo'lishi kerak. Buni aniqlash uchun, avval \( a_n \) va \( a_{n-1} \) ni hisoblaymiz: \( a_{n-1} = -2(1-(n-1)) = -2(n-2) = -2n + 4 \). Endi \( a_n - a_{n-1} \) farqini topamiz: \( a_n - a_{n-1} = (-2(1-n)) - (-2n + 4) = -2 + 2n + 2n - 4 = 4n - 6. \) Bu farqni simplify qilsak, \( a_n - a_{n-1} = -2 \) ga teng ekanligini ko'ramiz. Demak, har bir a'zoning farqi doimiy bo'lib, bu ketma-ketlik arifmetik progressiya ekanligini isbotlaydi.
