Answer:

72 and 73

Explanation:

let the first locker number be "y"

Hence, the next locker number [consecutive] would be "y+1"

Since the SUM is 145, we can add up the two and write and equation. Then simply solve algebraically. Shown below:


y+y+1=145\\2y+1=145\\2y=145-1\\2y=144\\y=(144)/(2)\\y=72

So, the 2 locker numbers are 72 and 73
