Answer:

The integers are 25,27,29

Explanation:

let n = the first integer
let n+ 2 = the second integer
let n+ 4 = the third integer

Then add them and set the three integers equal to 81.

# n + n+ 2 + n + 4 = 81 # combining like terms gives

# 3n + 6 = 81# subtract 6 from both sides

# 3n + 6-6 = 81-6 # this gives

# 3n = 75# divide both sides by 3

# (3n)/3 =75/3# the answer is

# n = 25#

The first integer is 25
The second integer is 27
the third integer is 29
