Many sequences do not follow the pattern of geometric or arithmetic. These sequences have their own patterns. Some can be modeled by other polynomial functions.

Example 1 The following sequence models triangular numbers:

1, 3, 6, 10, 15, 21, 28, 36, 45 …

This sequence is generated from a pattern of dots that form a triangle.
By adding another row of dots and counting all the dots, we can find the next number of the sequence.

OtherEx1-1


The symbolic pattern for this sequence is to add 2 to the first term, add 3 to the second term, add 4 to the fourth term and so on. This type of sequence has a constant second difference and can be modeled by the quadratic function OtherEx1-2.

Examples

Example 2 The following sequence models square numbers:

1, 4, 9, 16, 25, 36, 64 ....

Similar to the triangular numbers, square numbers make perfect squares from rows of dots. The symbolic pattern for this sequence can be modeled by the quadratic function OtherEx2-1.

Example 3 The following sequence models cube numbers.

1, 8, 27, 64, 125, 261 ....


The symbolic pattern for this sequence is to add 7 to the first term, add 19 to the second term, add 37 to the fourth term, and so on. This type of sequence has a constant third difference and can be modeled by the cubic function OtherEx3-1.
