In this video, we'll introduce the SEQUENCE function.

One of the new functions that comes with the dynamic array version of Excel is SEQUENCE. The SEQUENCE function lets you generate numeric sequences, which can be used for dates, times, and more.

The SEQUENCE function takes four arguments. The first argument, *rows* controls how many rows SEQUENCE returns. This argument is required.

The second argument, *columns*, controls the number of columns returned by SEQUENCE. *Columns* is optional and defaults to 1.

The third argument is called *start*. This is the starting point for the numbers returned by SEQUENCE, and can be any valid number.

The last argument is *step*. *Step* is the interval used between each number. The *step *argument is optional and defaults to 1.

Let's look at how these arguments work.

On this worksheet, we have a place to enter *rows, columns, start* and *step.*

To begin with, I'll set up the SEQUENCE function to use* rows* only.

Now, I'll get an error until I enter a value, since the empty cell is interpreted as zero, and zero is not valid for *rows.*

I'll set *rows* to 12.

Since the other three arguments all default to one, SEQUENCE returns a spill range that includes 12 *rows* and one *column.*

These values start at 1, and are incremented by 1.

Next, I'll connect the other arguments to the cells on the worksheet.

Again, we see an error, because the blank cells are interpreted as zero, and zero is not valid for *columns.*

When I set *columns* to 1, the error disappears.

I'll go ahead and set *start* and *step* to 1 as well.

Now we can easily visualize the output from SEQUENCE. If I use 2 or 3 for *columns*, we get a two-dimensional array.

If I use 5 for *columns*, we now have a grid that contains 60 numbers. Notice the numbers increment across, then down.

Next, I'll adjust the *start *argument.* Start *can be any valid number. For example, I can use 10, 100, -100, or a decimal value.

Finally, let's look at the *step* argument, which controls the interval between numbers.

Like* start*, this can be any valid number.

I can use zero, -1, 100, or, a decimal number like .01.
