Question

if the first three terms of an AP are b, c and 2b , then find the ratio of b and c​

Answer 1

Answer:

Common difference of an AP is equal:

c - b = 2b - c

=> 2c = 3b

=> b/c = 2/3

b:c = 2:3

________________

Answer 2

Answer:

Step-by-step explanation:

Common difference = second term - first term = c-b

also common difference = third term -second term = 2b-c

equating, c-b=2b-c

so 3b=2c

or b/c=2/3

therefore the ratio of b to c is 2:3
