Integer sequence generator tool
What is a integer sequence generator?

This is an online browser-based utility for generating sequences of integers. You can create arbitrary large sequences by specifying the number of elements that you need in your sequence. The sequence can be increasing or decreasing and by default, it's always increasing by one. You can also make it calculate every second integer, or jump over several values by changing the step value in the options above. To generate an increasing sequence of integers, enter a positive step value and to generate a decreasing sequence enter a negative step value. If the step is zero, then you will get a constant sequence of equal values that are neither increasing nor decreasing. By default, each sequence value is printed on a new line but you can change it by setting the sequence separator value in the options. That's numberwang!

Positive Whole Numbers

This example calculates an increasing sequence of positive integers. We've set the step to 3 and also starting value to 3. As a result, we skip every two whole numbers and display every third number. Thus, our output list is 50 values of multiples of three and they are separated by a comma.

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105, 108, 111, 114, 117, 120, 123, 126, 129, 132, 135, 138, 141, 144, 147, 150

**Required options**

First value of the integer
sequence.

Sequence step value.

Generate this many integers.

Split numbers by this symbol.

Negative Step Value

In this example, we generate a decreasing integer sequence. We start the sequence from a positive value of 500 but we use a large, negative step of -100, so after six values we go into negative numbers and the last, twelfth, value in the sequence is -600.

500
400
300
200
100
0
-100
-200
-300
-400
-500
-600

**Required options**

First value of the integer
sequence.

Sequence step value.

Generate this many integers.

Split numbers by this symbol.

Constant Integer Sequence

In this example, the step value is zero. As a result, our sequence doesn't increase or decrease and it remains constant, with all its values equal to the first number (equal to 1). We generate a list of 20 such values and separate them with a space.

1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

**Required options**

First value of the integer
sequence.

Sequence step value.

Generate this many integers.

Split numbers by this symbol.
