Vedclass · Answer

(C) The given $A.P.$ is $13, 8, 3, -2, \ldots$Here,the first term $a = 13$.The common difference $d = 8 - 13 = -5$.We need to find the $45^{th}$ term,denoted by $a_{45}$.The formula for the $n^{th}$ term of an $A.P.$ is $a_n = a + (n - 1)d$.Substituting the values $a = 13$,$n = 45$,and $d = -5$:$a_{45} = 13 + (45 - 1)(-5)$$a_{45} = 13 + (44)(-5)$$a_{45} = 13 - 220$$a_{45} = -207$.Therefore,the $45^{th}$ term is $-207$.
