Vedclass · Answer

(A) Given,the first term $a = -3$.The second term $a + d = 4$.Substituting the value of $a$ in the second term equation: $-3 + d = 4$.Therefore,the common difference $d = 4 + 3 = 7$.The formula for the $n^{	ext{th}}$ term of an $AP$ is $a_n = a + (n - 1)d$.For the $21^{	ext{st}}$ term $(n = 21)$:$a_{21} = -3 + (21 - 1) 	imes 7$.$a_{21} = -3 + 20 	imes 7$.$a_{21} = -3 + 140$.$a_{21} = 137$.
