help needed..answer only if u know otherwise better step back..​

Answer 1

Answer:

x = 9

x = 9mean = 10

Step-by-step explanation:

6 , 6 , x-2 , x+1 , x+3 , 14 , 15

mean = (6+6+x-2+x+1+x+3+14+15) ÷7

mean = (3x + 43)÷ 7

median = (7+1)/2 = 4th term

=> median = x+1

given

mean = median

=> (3x+43)/7 = x+1

=> 3x + 43 = 7(x + 1) = 7x+7

=> 7x-3x = 43-7

=> 4x = 36

=> x = 36/4

=> x = 9

now,

mean = (3x+43)/7 = (3×9 +43)/7

=> mean = (27+43)/7 = 70/7

=> mean = 10
