therefore:

Answer:
we know that mean of the data set is
Sum of all terms / total no. of terms
mean = 120+145+130+80+95+100+340+n / 8
140 = 1010+n / 8
140*8 = 1010 + n
1120 = 1010 + n
1120 - 1010 = n
110 = n
therefore the value of n should be 110

N=d-2
q=n+d =>q=(d-2)=q=2d-2
25q+5n+10d=525
replace q and n with d
25(2d-2) +5(d-2)+10d=525
50d-50+5d-10+10d=525
65d=585
d=9
n=7
q=16
