Question

. If the arithmetic mean of x, x+3, x+6, x+9, and x+12 is 10, then find its median

Answer 1

Answer:

x = 4

THE TERMS ARE 4, 7, 10, 13, 16

THE MEDIAN IS 10

Step-by-step explanation:

Total no. of terms = 5

THE TERMS ARE x, x + 3, x + 6, x + 9, x + 12

Mean = ( SUM OF ALL THE OBSERVATIONS ) / ( TOTAL NO. OF OBSERVATIONS ) = 10

( x + x + 3 + x + 6 + x + 9 + x + 12 ) / 5 = 10

( 5x + 30 ) / 5 = 10

( 5 ( x + 6 )) / 5 = 10

x = 10 - 6

x = 4

THE TERMS ARE 4, 7, 10, 13, 16

n = 5 ( odd )

The Median is 10
