the mean of x,x++,x+2,x+3,x+4,x+5,x+6
x+x+1+x+2+x+3+x+4+x+5+x+6 total divided by 7
7x+21 total divided by 7
then
7x+21=7
7x=7-21
7x=-14
x= -2
x+x+1+x+2+x+3+x+4+x+5+x+6 total divided by 7
7x+21 total divided by 7
then
7x+21=7
7x=7-21
7x=-14
x= -2
mean will be always positive
but here it is negative
the answer is x+3
how the ans is x+3? pls give briefly
the sum will be 7x+21 mean = 7x+21÷7 = x+3
