Question

数学题a:b:c:d:e:f:g=1:2:3:4:5:6:7,ab相差4,所有数总和是ab差的26倍
求所有的数
求解答

Answer 1

a:b:c:d:e:f:g=1:2:3:4:5:6:7-->
b=2a
c=3a
d=4a
e=5a
f=6a
g=7a
a-b=4或b-a=4
a=4或-4
b=8或-8
c=12或-12
d=16或-16
e=20或-20
f=24或-24
g=28或-28
a+b+c+d+e+f+g=28*4或28*(-4)
所以题目有问题

a+b+c+d+e+f+g=a+2a+3a+4a+5a+6a+7a=28a
28a=26*4或28a=-26*4
a=26/7或-26/7
b=52/7或-52/7
c=78/7或-78/7
d=104/7或-104/7
e=130/7或-130/7
f=156/7或-156/7
g=26或-26
