四、
六、34，等于前一个数+1 2 4 8 16 32
七、27，前两数相乘
八
九
十、 155 前两数相乘加1，
十一、36 前一数加 2 4 6 8 16
补充几个
四 1 从第3项起 每一项等于（前1项）-（前2项）
五 18 奇数项3+5=8 5+8=13 13+5=（18）
偶数项4*2=8 8*2=16 16*2=32
八 87 [6+(-1)=5 5*5=25] [25+6=31 31*(3-1)=62] [25+62=87 87*（8-7）=87]
（这个纠结了很久 才拼凑出来 如果你觉得不靠谱我也没办法）
九 90 4/4=1 6/4=1.5 12/6=2 30/12=2.5 以此类推
