{a 1 , a 2 …………., a 4 ……..} is a progression where a n = n 2 /(n 3 +200). The largest term of this progression is: a 6 a 7 a 8 none

Question

Y RAJYALAKSHMI · Answer

On differentiating w.r.t n & equating to 0, we get (n 3 + 200) * 2n – n 2 * (3n 2 ) = 0 => n 3 = 400 => n = 7.3 Since n is a naturanl no, on verification we can find that a n attains maximum value at n = 7 Ans = a 7
