Let the unknown no. be p

It is given that :-

  2.831 + 8.04 + p = 14.593

Thus, in order to find p, we have to add the first two given nos. and subtract the result from the total sum.

i.e.,     2.831

       + 8.040 

       bottom enclose space space space space space space space space space space space space space end enclose

        10.871 

      bottom enclose space space space space space space space space space space space space space end enclose

Now, subtract 10.871 from 14.593

  14.593 - 10.871 = 3.722

Thus, the third number is 3.722
