(1)1,3,2,6,3,9,(4),(12),(5).
(2)9,13,17,21,(25 ),(29),(33).
(3)1,4,9,16,25,36,(49),(64),(81).
(4)6,7,9,12,16,21,(27),(34),(42).

(1)(4),(12),(5)
(2)( 25 ),(29),(33)
(3)(49),(64),(81)
(4)(27),(34),(42)

1,3,2,6,3,9,(4),(12),(5)隔着一个数看,会发现规律
9,13,17,21,(25),(29),(33)加4
1,4,9,16,25,36,(49),(64),(81)1的平方 2的平方 3的平方……
6,7,9,12,16,21,(27),(34),(42)加1 加2 这样加上去
