I started the main sequence ten minutes ago, assuming you'd be on time.

However, it is probably not a part of the main sequence, as seen in its young age.

They then move across from the main sequence into the giant branch.

As such, these stars are likely on the main sequence.

They stay on the main sequence for millions or billions of years.

After this happens, the star is no longer on the main sequence.

A star located on the upper main sequence may only last a few million years.

After 11 billion years on the main sequence, the Sun will change course.

Such stars are said to be in the main sequence.

The table below shows typical values for stars along the main sequence.
