A) 21st
B) 22nd
C) 23rd
D) 24th
Correct Answer: C
Solution :
Here, first term, \[a=5\] Common difference, \[d=8\] Let 181 be the nth i.e., \[{{a}_{n}}=181\] \[\therefore \] \[181=5+\,(n-1)8\] \[\therefore \] \[176=\,(n-1)8\] \[\therefore \] \[n-1=\frac{176}{8}=22\] \[\therefore \] \[n=23\] Hence, 181 is the 23rd term.
