its third term.​

Answer 1

The third term is 25/3

Step-by-step explanation:

According to the given proportion,

→ First term : second term : : third term : fourth

→ 6 : 18 : : third term : 25

→ 6/18 = third term/25

→ 6*25/18 = third term [multiplying both sides by 25]

→ 1*25/3 = third term

→ 25/3 = third term.
