If sides of

\triangle A B C

are

a, b

and

c

such that

2 b=a+c

, then exhaustive range of

\frac{b}{c}

View answer and explanation

Correct option: C

\left(\frac{2}{3}, 2\right)

Option C (

\left(\frac{{2}}{{3}}, 2\right)

) is correct because the given condition

2b = a+c

and triangle inequalities lead to the range of

\frac{{b}}{{c}}

being between

\frac{{2}}{{3}}

and 2.
