Question

check whether 7,49,343 are in continued proportion or not​

Answer 1

Step-by-step explanation:

let a=7, b=49, c=343

if a, b, c are in continued proportion

then, b^2=ac

49^2=7×343

49×49=7×7×49

49×49=49×49

here we see that, L.H.S = R.H.S

hence, a, b, c are in continued proportion

Answer 2

Yes it is continued proportion.
