等差数列的推广。如果数列{an}的每相邻两项的差作成的数列{an+1-an}是一个公差不为零的等差数列,就称{an}为二阶等差数列,如果数列{an+1-an}是二阶等差数列,就称原数列{an}为三阶等差数列。一般地,如果{an+1-an}是K阶等差数列,就称原数列{an}为K+1阶等差数列,二阶以及高于二阶的等差数列统称为高阶等差数列。普通等差数列称为一阶等差数列。例如,数列12,22,32,…,n2,…的相邻项的差作成数列3,5,7,…,2n+1,…,是等差数列,公差为2,所以原数列是二阶等差数列。数列13,23,33,…,n3,……的相邻项的差数列是7,19,37,61,……,再作相邻项之差,得12,18,24,…,这是等差数列,公差为6。所以原数列是三阶等差数列。
