a, a - b, a - 2b, a - 3b,...... क्रमिकेचे 10वे पद 20 आणि 20वे पद 10 आहे.
गणना:
10वे पद = a - 9b = 20 --(1)
20वे पद = a - 19b = 10 ---(2)
समीकरण (1) मधून समीकरण (2) वजा केल्यास:
a - 9b - (a - 19b) = 20 - 10
⇒ a - 9b - a + 19b = 10
⇒ 10b = 10
⇒ b = 1
समीकरण (1) वरून:
a - 9 (1) = 20
⇒ a = 20 + 9 = 29
आता, xवे पद = a - (x - 1)b
⇒ 29 - (x - 1) (1)
⇒ 29 - x + 1 = 30 - x
∴ क्रमिकेचे xवे पद 30 - x आहे.
