We know that the three integers are consecutive and the units digit of c*a = 4.
4*6 = 24 which has units digit of 4, so let our sequence be
0 < 4 < 5 < 6
We can see that the units digit of the middle term is 5
4*6 = 24 which has units digit of 4, so let our sequence be
0 < 4 < 5 < 6
We can see that the units digit of the middle term is 5
