Question

check whether the following numbers are in continued proportion .4,20,100

Answer 1

Answer:

Step-by-step explanation:

in continued proportion, 2nd term repeats itself,

since product of means = product of extremes,

4 * 100 should be equal to 20*20

LHS = 4*100 = 400

RHS = 20*20 = 400

Since LHS=RHS,

This sequence is proportional

Answer 2

Answer:

Step-by-step explanation:

4 * 5 =20

20 * 5 = 100

100 * 5 = 500

500 * 5 = 2500

2500 * 5 = 12500
