1,4,9,16,( 25),( 36)
1,2,4,7,11(16 ),(22 )
16,4,1,1/4 ( 1/16)
1/5,0.4,3/5,0.8(1 ),( 6/5)
7,5,14,4,21,3( 28),( 2)

25，36， 16，23， 1，1.2， 28，2

1,4,9,16,( 25),(36 ) 即n的平方
1,2,4,7,11(16 ),( 22) 前项减去后项分别为n
16,4,1,1/4 1/16 四分之倍
1/5,0.4,3/5,0.8( 1),( 1.2) 0.2 0.40.6 自己可以看懂撒
7,5,14,4,21,3(28 ),( 2) 奇数项 7 14 21 28 偶数项为 5 4 3 2
求给分呵呵
