A) 28
B) 22
C) - 38
D) \[-48\frac{1}{2}\]
Correct Answer: B
Solution :
(b): Here, \[a=-3,d=-\frac{1}{2}-(-3)=-\frac{1}{2}+3=\frac{-1+6}{2}=\frac{5}{2}\] \[\therefore {{a}_{1}}=a+(n-1)d;\,\,{{a}_{11}}=-3+(11-1)\frac{5}{2}\] \[=-\,3+10\times \frac{5}{2}=-\,3+25=22\]You need to login to perform this action.
