Answer:
l'm giving you a example please put 7,14,15 instead of
Step-by-step explanation:
Therefore, 12, x, 8 and 14 are in proportion i.e., 12 : x = 8 : 14
⇒ x × 8 = 12 × 14, [Since, the product of the means = the product of the extremes]
⇒ x = (12 × 14)/8
⇒ x = 21
Therefore, the second term of the proportion is 21.
