Vedclass · Answer

(C) The given $A.P.$ is $34, 27, 20, 13, \ldots$Here,the first term $a = 34$ and the common difference $d = 27 - 34 = -7$.We need to find the term $n$ such that $a_n = -519$.The formula for the $n^{th}$ term of an $A.P.$ is $a_n = a + (n - 1)d$.Substituting the values: $-519 = 34 + (n - 1)(-7)$.$-519 - 34 = (n - 1)(-7)$.$-553 = (n - 1)(-7)$.$n - 1 = \frac{-553}{-7} = 79$.$n = 79 + 1 = 80$.Therefore,the $80^{th}$ term of the $A.P.$ is $-519$.

Which term of the $A.P.$ $34, 27, 20, 13, \ldots$ is $-519$ (in $^{th}$)?
