hey pankaj ur answer is
210=21 by2(2a+20d)
210×2by21=(2a+20d)
420 by 21=(2a+20d)
20=2a+20d
dividing by 2 we get
10=a+10d
we want to know the value of 11th term
=a+(11-1)d
=a+10d
=10
210=21 by2(2a+20d)
210×2by21=(2a+20d)
420 by 21=(2a+20d)
20=2a+20d
dividing by 2 we get
10=a+10d
we want to know the value of 11th term
=a+(11-1)d
=a+10d
