Answer:
The third term is 8.
Given : The 1st, 2nd and 4th terms of a proportion are 12,21 and 14 respectively.
To find : The third term ?
Solution :
If the four terms are in proportion
a:b:: c:d
then
\frac a/b=\frac c/d
The 1st, 2nd and 4th terms of a proportion are 12,21 and 14 respectively.
i.e. a=12, b=21 and d=14
Substitute,
\frac12/14=\frac c/14
c=\frac12\times 14/21
c=8
