Two series, s1 and s2 each of 150 termare1,5,9......and 3,6,9.......respectively.how many terms of
s1 and s2 are identical ?

• 1,5,9,13,17,.....,(1+149*4=597)
  3,6,9,12,15,....,(3+149*3=450)
  
  series of common terms
  9,21,33,45,... < = 450
  tn=a+(n-1)d
  put a=9 tn=441 d=12
  ans n=37

  3,6,9,12,15,....,(3+149*3=450)
  
  series of common terms
  9,21,33,45,... < = 450
  => n = 36 terms are identical

• 450 is the last digit, not total term

• how do u know that there are 450 common terms @rakesh

• from how an=441......in series si and s2 we have to find the common one if we use 450 as the identical term then in series one 450 is not present as a+(n-1)d=450 is in fraction n can not be in fraction number should be divisible by putting 441 is correctly divisible in both the series
