x,y,z are three terms in GP and a,b,c are three terms in AP
prove that (xb÷xc)(yc÷ya)(za÷zb)=1
Homework Equations
The Attempt at a Solution
(xb-c)(yc-a)(za-b)
since x y z are in GP
xb-c÷yc-a=yc-a÷za-b
(xb- c)(za-b)=yc-a(yc-a)
Conditional identity consisting of AP and GP is a mathematical concept that states that if two sequences are arithmetic and geometric progressions, respectively, and have the same first term and common difference/ratio, then their sum or product will also form an arithmetic or geometric progression, respectively.
Conditional identity consisting of AP and GP is useful in solving various mathematical problems involving sequences and series. It allows us to find the sum or product of a series without having to manually calculate each term.
Yes, conditional identity consisting of AP and GP can be used in real-life situations, particularly in finance and economics. It is commonly used in calculating compound interest and in analyzing investment growth over time.
The conditional identity consisting of AP and GP can be proved using mathematical induction. By assuming the identity is true for a specific value of n, we can show that it is also true for n+1, thus proving the identity for all positive integers.
While conditional identity consisting of AP and GP is a powerful tool in mathematics, it has its limitations. It can only be used for sequences with a common difference/ratio and cannot be applied to divergent sequences. Additionally, it may not be applicable in certain complex mathematical problems.
