Question

If x ,4, y are successive terms in arithmetic sequence and x, 3 ,y are successive terms in geometric sequence. Calculate 1/x +1/y.​

Answer 1

Step-by-step explanation:

Given If x ,4, y are successive terms in arithmetic sequence and x, 3 ,y are successive terms in geometric sequence. Calculate 1/x +1/y.​

• According to property of A.P t he middle number is doubled hence we can write as  
• So x + y = 4 x 2
• Or x + y = 8
• Now x,3,y are in G.P. So
• 3 = √xy
• Or xy = 9
• Now we need to find 1/x + 1/y
•                               = x + y / xy
•                               = 8 / 9
