Question

The first,third and fourth terms of a proportion are 12,8 and 14 respectively. Find the second term.​

Answer 1

Let the second term be x.

Therefore, 12,x,8,14 are in proportion i.e., 12:x=8:14

$\frac{12}{x} = \frac{8}{14} \\ \\ 8x = 12 \times 14 \\ \\ 2x = 3 \times 14 \\ \\ x = 3 \times 7 = 21</p><p>$

Hence, The answer is 21✅️
