If one geometric mean G and two arithmetic mean A & B are inserted between two given quantities , then find (2A-B)(2B-A) a) 2G b) G C) G^2 d) G^3?
Verified Answer
If one geometric mean G and two arithmetic mean A & B are inserted bet...
Let the two nos. Be a and b.
Geometric mean (G) between a and b will be √ab
G^2 = ab ---------(1)
Given : p and q are 2 arithmetic mean between a and b
Then A.P. is a,p,q,b
--> p=(a+q)/2 and q=(p+b)/2
--> 2p = a+q and 2p = p+b ------ (2)
To prove : G^2 =(2p-q)(2q-p)
RHS = (2p-q)(2q-p)
= (a+q-q)(p+b-p) {from (2)}
= ab
= G^2 {proved above in (1)}
= LHS
HENCE PROVED
