Sergey and Misha, while walking in the park, stumbled upon a glade surrounded by lindens. Sergey walked around the glade, counting the trees. Misha did the same, but started from a different tree (although he went in the same direction). The tree that was 20th for Sergey was 7th for Misha, and the tree that was 7th for Sergey was 94th for Misha. How many trees grew around the glade?

#
Between the first and second mentioned trees, Misha counted another $94-7-1=86$ trees. And Sergei between the second tree and the first tree counted $20-7-1=12$ trees. Therefore, around the clearing, there are $86+$ $12=98$ trees and two more mentioned trees, that is, exactly 100 trees.

## Answer

100.
