Constraint on the equation of state parameter ($\omega$) in
  non-minimally coupled $f(Q)$ gravity
  We study observational constraints on the modified symmetric teleparallel
gravity, the non-metricity $f(Q)$ gravity, which reproduces background
expansion of the universe. For this purpose, we use Hubble measurements,
Baryonic Acoustic Oscillations (BAO), 1048 Pantheon supernovae type Ia data
sample which integrate SuperNova Legacy Survey (SNLS), Sloan Digital Sky Survey
(SDSS), Hubble Space Telescope (HST) survey, Panoramic Survey Telescope and
Rapid Response System (Pan-STARRS1). We confront our cosmological model against
observational samples to set constraints on the parameters using Markov Chain
Monte Carlo (MCMC) methods. We find the equation of state parameter
$\omega=-0.853^{+0.015}_{-0.020}$ and $\omega= -0.796^{+0.049}_{-0.074}$ for
Hubble and Pantheon samples, respectively. As a result, the $f(Q)$ model shows
the quintessence behavior and deviates from $\Lambda$CDM.
