Solve the Problem $\bar { x } = \frac { c + d } { 2 }$

question 134

Multiple Choice

Solve the problem.
-The arithmetic mean (average) of two numbers c and d is given by $\bar { x } = \frac { c + d } { 2 }$ . The value $\bar { x }$ is equidistant between c and d, so the sequence $c , x , d$ is an arithmetic sequence. Inserting k equally
Spaced values between c and d, yields the arithmetic sequence c, $\bar { x } _ { 1 } , \bar { x } _ { 2 } , \bar { x } _ { 3 } , \bar { x } _ { 4 } , \ldots , \bar { x } _ { n }$ , d. Use this
