If A = 2,5,8,.....302 and
B = 3,5,7.....303,
the no. of common terms of A and B is ?
a. 53
b. 52
c. 51
d. 50

• Ans=50
  
  Series is :
  A= 2,5,8,11,14,17,.......................296,299,302
  B=3,5,7,9,11,13,15,17.............................297,299,301,303
  
  we see in above series.....common term in series is in difference of 6
  
  so,
  now, Common term series is :
  5,11,17,23,...................299
  then
  no of common term is= >An=A1+(N-1)d
  here An=299, A1=5, d=6
  => 299=5+(N-1)6
  =>299=5+6N-6
  =>6N=300
  => N=50
