Answer:

8551

Step-by-step explanation:

  • The midpoint of two numbers can be found by finding the mean of the two numbers
  • Midpoint = 8516 + 8586 / 2
  • We clearly see both numbers start with the digits '85' therefore their midpoint will also start with '85'
  • The remaining two digits on those two numbers should be added and divided by 2
  • ⇒ 16 + 86 / 2 = 102/2 = 51
  • Midpoint = 8551
