chapter11 question 3
Asked by sameeksha | 24 Feb, 2018, 08:11: AM
If a,b,c are in AP it follows that
a+c=2b……..(1)
and a,x,b and b,y,c are in individual GPs which follows
x2 = ab …….(2)
y2 = bc ……..(3)
Adding eqn 2 and 3 we get,
x2+y2 = ab+bc
= b(a+c)
= b x 2b ( from eqn 1)
= 2b2
So we get x2+y2 = 2b2
which shows that x2 ,b2 ,y2 are in AP......Question was incomplete will be replaced
