If the first three terms of an A.P are b,c and 2b ,then find tbe ratio of b and c |
|
Answer» b+2b=2c (sum of 1st and 3rd term is equal to twice of 2nd term)3b=2cC=3b/2 Now,b:c= b:(3b/2)b:c= 2b:3bb:c=2:3 ........answer givenb ,c and 2 b are in Apthen the common differencesc - b = 2b-c-b- 2b = -c - c-3b = -2cthen,I hope it helps you Best of luck It is given that first three terms of an A.P are b, c and 2b. Divide both sides by c. Now divide both sides by 3. Therefore, the ratio of b and c is 2:3. |
