jhil  (9 years ago)

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

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
=> n = 36 terms are identical

Raghav gupta  (9 years ago)

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
