for the data 2,9,x+6,2x+3,5,10,15 if mean is 7,then the mode is​

1. Answer:

   as n = 7 which is an odd number

   mean = (n+1) th observation

   ( 2)

   = (7+1) th obervation

   (2)

   = 4th observation

   as mean= 7

   4th observvation=2x+3=7

   x= 2

   x+6= 8

   therefore 5 is the most occuring observation

   mode=5
