To find the lower quartile take the number of terms=n=12
to find the lower quartile take the equation (n+1)/4= 3.25
this means that the lower quartile will be at the 3.25th position int he sequence when all the terms are ordered from smallest to largest. so when ordered: 12 19 19 19.5 20 28 28 28.5 34 36 45 45
so the lower quartile is between 19 and 19.5 exactly 19.125
