Question

Show that36,90,225 are in continued proportion??

Answer 1

We know that a/b=b/c
Therefore, 36, 90, 225 are not in continued proportion because 36/90 is not equal to 90/225

Answer 2

If a, b, c are in continued proportion, then b² = ac .

Here,

=> a = 36 , b = 90 , c = 225 .

If 36,90,225 are in continued proportion then;

90² = 36 × 225

8100=8100 .

LHS = RHS

Hence, 36,90,225 are in continued proportion.
