Answer 2

Step-by-step explanation:

Let the third number be X

Proportion= 10:7::x:210

7*x = 210*10

7x= 2100

x= 2100/7

x = 300

Therefore the fourth term is 300.

Proof of 300 is right answer: ( put the value of x in proportion)

therefore = 10:7::300:210

= 10*210=300*7

= 2100= 2100

therefore 300 is correct answer.
