उतर :-

माना दी गई सूची का n वा पद 305 है l

तब,

→ पहला पद = a = 5

→ d = 11 - 5 = 6

अत,

→ T(n) = a + (n - 1)d

→ T(n) = 305

→ a + (n - 1)d = 305

→ 5 + (n - 1)6 = 305

→ 5 + 6n - 6 = 305

→ 6n - 1 = 305

→ 6n = 305 + 1

→ 6n = 306

→ n = 51

चूंकि n का मान प्राकृतिक संख्या है l इसलिए हम कह सकते है कि, दी गई सूची का 51 वां पद 305 है l
