Answer 2

Step-by-step explanation:

The proof is shown below

Step-by-step explanation:

we have to show 25,35 and 49 are in continued proportion

Three variables are said to be in continued proportion if the ratio between the first and the second is equal to the ratio between the second and the third.

i.e. a : b = b : c

If the numbers are in continued proportion then

25:35::35:49,

25\times 49=35\times 3525×49=35×35

1225=12251225=1225

LHS=RHS (PROVED)

Hence, 25,35 and 49 are in continued proportion
