Answer 1

Answer:

Hey mate here is your answer.//

Step-by-step explanation:

It is given that three numbers are in the ratio 2:5:7.

Let the three numbers are 2x, 5x, 7x.

If 7 is subtracted in middle term it forms an auththetic sequene

2x, 5x-7, 7x are in authethetic sequence .

If a,b,c are in auththetic sequence, then

2b=a+c,

2(5x-7)=2x+7x,

10x-14=9x,

10x-9x=14,

x=14.

The value of x is 14.

The auththetic sequesnce is

2(14), 5(14)-7, 7(14)

28, 63, 98

Therefore the required auththetic sequence is 28, 63, 98.
