Answer:

236

Step-by-step explanation:

Louis's average before the sixth round:

=(214+231+242+223+270)÷5

=1180÷5

=236

After the sixth round:

236=(214+231+242+223+270+unknown value) ÷6

236= (1180+unknown value) ÷6

Multiple both sides by 6

236X6=1180 + unknown value

1416=1180 + unknown value

1416 - 1180 = unknown value

Unknown value =236
