An infinite sequence of possitive integers is called an "aplha sequence"if the number of even integers in the sequence is finite . if S is an infinite sequence of positive integers,is S an alpha sequence?"如果在某个数列中偶整数的数量是有限的,则一个正整数的无限或无穷大数列被称为aplha数列.假如S是一个正整数的有限数列,那S是alpha数列吗?"
(1) The first ten integers in S are even?(在S数列中,第一个十位数的整数是偶数吗?)
(2) An infinite number of intergers in S are odd?(在S数列中,整数的无限大的数是奇数吗?

一个无限正整数数列被称为"alpha sequence"如果这个数列里头的偶数个数是有限个的话.假设S是一个无限的正整数数列,S是"aplha sequence"吗?
(1) The first ten integers in S are even?(在S数列中,第一个十位数的整数是偶数吗?)
S数列里头的前十个数是整数
(2) An infinite number of intergers in S are odd?(在S数列中,整数的无限大的数是奇数吗?
S数列里头有无限个奇整数
