The values of `xyz` is `15/2` or `18/5` according as the series `a, x, y, z, b` is an `AP` or `HP.` Find the values of `a & b` assuming them to be positive integer.

The value of xyz is 55 or (343)/(55) according as the series a,x,y,z,b is an AP or HP. Find the values of a and b given that they are positive integers.

The value of xyz is 55 or (343)/(55) according as the series a,x,y,z,b is an AP or HP. Find the values of a and b given that they are positive integers.

The value of xyz is 55 or (343)/(55) according as the series a,x,y,z,b is an AP or HP. Find the values of a and b given that they are positive integers.

The value of xyz is 55 or (343)/(55) according as the series a,x,y,z,b is an AP or HP. Find the values of a and b given that they are positive integers.

The value of xyz is 55 or (343)/(55) according as the series a,x,y,z,b is an AP or HP. Find the alues of a and b given that they are positive integers.

The value of xyz is 55 or 343/55 according as the sequence a, x, y, z, b is an A.P. or H.P. Find the sum (a + b) given that a and b are positive integers

The value of xyz is 55 or 343/55 according as the sequence a,x,y,z,b is an H.P or A.P Find the sum (a+b) given that a and b are positive integers

If 18, a, (b-3) are in AP, then find the value of (2a-b).

The value of x+y+z is 15 if a,x,y,z,b are in AP while 1/x+1/y+1/z is 5/3 if a,x,y,z,b are in HP ,then the value of a is

If a, x, y, z, b are in A.P., then value of xyz is 35/3 and if a, x, y, z, b are in H.P., then value of xyz is 75/7, where a and b are given positive integers. Then value of (ab) is
