Hello Student,
Please find answer to your question below

For any system of the circles whose centres lie on the straight line, the number of radical axis will be equal to number of radical centres,
For example:
Consider two circles
Number of radical axis will be one & number of radical centre will be one.
Consider three circles whose centre lie on line
Number of radical axis will be two & number of radical centre will be two.
Consider ‘n’ circles whose centre lie on line
Number of radical axis will be ‘n-1’ & number of radical centre will be ‘n-1’.
