Answer:
384
Step-by-step explanation:
sum of numbers= average * number of numbers
sum of 5 positive integers =436 *5 =2180
sum of first two numbers =344 * 2 =688
sum of last two numbers = 554 * 2 =1108
third number = sum of 5 positive integers -(sum of first two numbers + sum of last two numbers)
=2180-(688+1108)
=2180-1796
=384
