If 1/3 ,m,1,n form a GP the product of m and n

To form a geometric progression (GP), we know that the ratio between any two consecutive terms must be the same.

Let's consider the given terms: 1/3, m, 1, n.

The ratio between the first and second terms is: m / (1/3) = 3m.

The ratio between the second and third terms is: 1 / m.

The ratio between the third and fourth terms is: n / 1 = n.

Since the ratio between the second and third terms is 1/m and the ratio between the third and fourth terms is n, we can equate them:

1/m = n

Solving for m, we get:

m = 1/n

Therefore, the product of m and n is:

m * n = (1/n) * n = 1

or, since 1 is the geometric mean of m and n,

√(mn) = 1
so mn = 1

Yes, you are correct. Since 1 is the geometric mean of m and n, we can also find the product of m and n by taking the square root of their product and setting it equal to 1.

√(mn) = 1

Squaring both sides:

mn = 1

Therefore, the product of m and n is indeed 1.

To determine the product of m and n in the geometric progression (GP) formed by 1/3, m, 1, and n, we can use the formula for a GP.

In a GP, each term is obtained by multiplying the previous term by a constant called the common ratio (r). In this case, we have 1/3, m, 1, and n.

So, we can write the relationship between these terms as follows:

m = (1/3) * r
1 = m * r
n = 1 * r

To find the product of m and n, we need to eliminate the common ratio, r. We can do this by dividing the second equation by the first:

1/3 * r / (1/3) = (m * r) / (1/3)
r = 3 * m

Now, substitute this value of r into the third equation:

n = 1 * (3 * m)
n = 3 * m

Therefore, the product of m and n is (3 * m) * (3 * m), which simplifies to 9 * m^2.
