Answer: +21

Step-by-step explanation:

Based on the information given, we are informed that at first down, a football team lost 16 yd and they after two downs, the team had an overall gain of 5 yd.

The number of yards that were gained on second down can be represented by x. We can then form the question as an equation as:

x - 16 = 5

x = 5 + 16

x = 21

The team gained 21 yards.
