The fourth proportion to 2a ,a³,c is?
Calculating the Fourth Proportion to 2a, a³, c
To find the fourth proportion to 2a, a³, and c, we need to first understand what a fourth proportion is. In a proportion, four quantities are said to be in proportion when the ratio of the first pair is equal to the ratio of the second pair.

Identify the Given Values
In this case, the given values are:
- First term: 2a
- Second term: a³
- Third term: c

Formulating the Proportion
To find the fourth proportion, we set up the proportion as follows:
(2a)/(a³) = (c)/(x)

Solving for the Fourth Proportion
Cross multiplying, we get:
(2a) * x = (a³) * c
2ax = a³c
x = (a³c)/(2a)
x = ac/2
Therefore, the fourth proportion to 2a, a³, and c is ac/2. This means that ac/2 is the fourth term in the proportion with the given terms 2a, a³, and c.
