#n < 4#

Explanation:

Remember:

Things you can do to both sides of an inequality without changing the direction of the inequality:
[1]#color(white)("XXX")#Add or subtract the same amount to both sides;
[2]#color(white)("XXX")#Multiply or divide both sides by any amoun greater than zero.

Inverting inequalities:
[3]#color(white)("XXX")#If #a < b# then #b > a#, and visa versa.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Given
#color(white)("XXX")1 > -1 + n/2#

Adding #1# to both sides
#color(white)("XXX")2 > n/2#

Multiplying both sides by #2#
#color(white)("XXX")4 > n#

Inverting:
#color(white)("XXX")n < 4#
