WHAT IS AN ARITHMETIC PROGRESSION?

IF YOU RIGHT SEVERAL TERMS SUCH THAT THE DIFFERENCE BETWEEN THE SUCCESSIVE TERM WITH THE PRECEDING TERM IS CONSTANT OR SAME THAN THE SERIES OR PROGRESSION YOU FORMED IS KNOWN AS ARITHMETIC PROGRESSION.

THE COMMON DIFFERENCE IN ARITHMETIC PROGRESSION IS SAME SO USING THIS FUNDA I CAN SOLVE YOUR QUESTION.

$b \: c \: and \: 2b \: are \: in \: progression \\ \\ c - b = d......(1) \\ where \: d \: is \: the \: common \: difference \\ we \: talking \: about \\ \\ 2b - c = d......(2) \: \\ d \: is \: same \: for \: all \: the \: terms \: in \: \\ progression \\ \\ from \: (1) \: and \: (2) \\ \\ c - b = 2b - c \\ c + c = 2b + b \\ 2c = 3b \\ \frac{2}{3} = \frac{b}{c}$
