Question

check whether 7, 49,343 are in a continued proportion

Answer 1

a=7, b= 49 and c= 343

Continued proportion is also known as mean Proportional.

If b is a mean Proportion between a and c

∴ b²=ac

49²=7×343

2401=2401

Therefore, it is a continued proportion

Answer 2

Yes

7 × 7 = 49 ( 7^2 = 49)

and

7 × 7 × 7 = 343 (7^3 = 343)

so these numbers are in continued proportion
