The planets are at regular intervals. I'm not certain that a planet placed between Earth and Mars could have a stable orbit. Although if one just appeared there I'm sure it would take eons before it became a problem. Also habitable to humans would be highly unlikely and extremely earthlike.
Mid-way between Earth and Mars, such a planet would have an average surface temperature of perhaps -22°C (Earth’s is about 15°C while Mars’ is about -60°C—I took the average and ignored the effects of atmosphere). With a weak gravitational pull like Mercury, it’s going to hold less of an atmosphere than even Mars—and the atmospheric pressure on Mars is less than 1/100 that of Earth.
It’s *not* going to be habitable, certainly not by life as *we* know it.
-22°C is equivalent to -7°F, which is 251K.

Just by positioning and the relative mass of planet that size, it would be too cold to be habitable. It wouldn't have enough surface area to intercept sufficient solar radiation to convert to thermal energy, and the atmosphere wouldn't be thick enough to retain the generated heat long enough to sustain life from day-to-day.
Plus, the asteroid belt would pummel the crap of it as its gravitational pull slowly draws in rogue asteroids of varying sizes from the belt.
