Vedclass · Answer

(A) The given $A.P.$ is $9, 13, 17, 21, \ldots$Here,the first term $a = 9$.The common difference $d = 13 - 9 = 4$.We need to find the $12^{th}$ term $(a_{12})$.The formula for the $n^{th}$ term of an $A.P.$ is $a_n = a + (n - 1)d$.Substituting the values: $a_{12} = 9 + (12 - 1) 	imes 4$.$a_{12} = 9 + 11 	imes 4$.$a_{12} = 9 + 44$.$a_{12} = 53$.Therefore,the $12^{th}$ term is $53$.
