Answer:
160
Explanation:
Consecutive numbers have a difference of 1 between them.
Let n be the first number then n + 1 and n + 2 are the second and third numbers. Summing them gives
n + n + 1 + n + 2 = 477, that is
3n + 3 = 477 ( subtract 3 from both sides )
3n = 474 ( divide both sides by 3 )
n = 158
The 3 consecutive numbers are 158, 159, 160
The third number is 160
