An astrophysicist compiles a dataset of main sequence stars within a newly catalogued stellar cluster. The table below presents the mass, luminosity, and estimated main sequence lifetime for five of these stars.

Star DesignationMass (in Solar Masses, M⊙M_{\odot}M⊙​)Luminosity (in Solar Luminosities, L⊙L_{\odot}L⊙​)Main Sequence Lifetime (years)
Cluster-A185.08.0 × 1053.0 × 106
Cluster-B412.01.1 × 1044.0 × 107
Cluster-C22.53.5 × 1016.0 × 108
Cluster-D91.01.01.0 × 1010
Cluster-E50.24.0 × 10-31.0 × 1012

Using the data in the table, state the relationship between a main sequence star's mass and its main sequence lifetime.
