Question

301 is a term of AP 5 ,11 ,17 ,23.......​

Answer 1

Answer:

......................a+b + b+ a

Answer 2

let aⁿ = 301

common difference, d = a² - a¹ = 11 - 5 = 6

first term, a = 5

we know that,

aⁿ = a + (n - 1)d

$n = \frac{ {a}^{n} - a }{d} + 1 \\ n = \frac{301 - 5}{6} + 1 = \frac{296}{6} + 1 \\ n = \frac{296 + 6}{6} = \frac{302}{6} = not \ \: a \\ natural \: number$

hence, 301 is not a term of the AP
