An orchard owner recorded the weight, in pounds, of all nectarines that grew on a dwarf nectarine tree during each growing season after the tree's transplantation. The scatterplot shows this weight, in pounds, for each growing season after the tree's transplantation.

The x-axis represents growing season after transplantation, and the y-axis represents weight of nectarines in pounds.

What was the average weight, in pounds, of all nectarines that grew on the tree during the first $5$ growing seasons after the tree's transplantation?
