Question

 FIND THE MEDIAN OF FIRST 8 ODD NUMBERS​

Answer 1

Answer:

Address the formula, input parameters & values.

Input parameters & values:

The number series 1, 3, 5, 7, 9, . . . . , 15.

The first term a = 1

The common difference d = 2

Total number of terms n = 8

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 8/2 x (1 + 15)

= (8 x 16)/ 2

= 128/2

1 + 3 + 5 + 7 + 9 + . . . . + 15 = 64

Therefore, 64 is the sum of first 8 odd numbers.

Answer 2

Answer:

9 is the median of the first 8 odd numbers

Step-by-step explanation:

first 8 odd numbers:-1,3,5,7,9,11,13,15

              therefore,(n)=odd

                  =>median =$\frac{1}{2}$ x( $\frac{8}{2}$ th term +  $\frac{8}{2}$+1   th term)

                  =>$\frac{1}{2}$ x( 4 th term   + 5 th term)

                  => $\frac{1}{2}$ x ( 9 + 11)

                      $\frac{1}{2}$  x  18

                        9
