Answer
23 and 24.
Explanation
let the first integer be x.
The next integer would be x + 1
Now form the equation
x + (x+1) = 46
x + x + 1 = 46
2x + 1 = 46
2x = 46 - 1
x = 45
x = 22.5 This is not an integer.
Since the question is asking for the least possible integer, unless we use 23 ≅22.5
The first integer been 23, the other one would be (23 + 1) = 24.
The least possible pair would be 23 and 24.
