I hope this helps.
Add them together then subtract 10 then divide by 8%
If it is a 32:1 then the answer is somewhere around 6.125 inches
32 : 1 = 196 : X
32X = 196
X = 196/32
X= 6.125
For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72
