(B) The given $A.P.$ is $12, 21, 30, \ldots, 363$.Here,the first term $a = 12$ and the common difference $d = 21 - 12 = 9$.The last term $l = 363$.To find the $n^{th}$ term from the end of an $A.P.$,we use the formula: $n^{th}$ term from end $= l - (n - 1)d$.Here,$n = 12$,$l = 363$,and $d = 9$.Substituting the values: $12^{th}$ term from end $= 363 - (12 - 1) 	imes 9$.$= 363 - (11 	imes 9) = 363 - 99 = 264$.Thus,the $12^{th}$ term from the end is $264$.

For the finite $A.P.$ $12, 21, 30, \ldots, 363,$ find the $12^{th}$ term from the end.
