What is the remainder when the positive integer n is divided by 3?

(1) The remainder when n is divided by 2 is 1.

(2) The remainder when n + 1 is divided by 3 is 2

Lets take another approach if you couldnt derive what bunnel did.

1. remainder n/2 =1

lets try some numbers:

n=3 remainder =1 n/3 remainder =0

n=5 remainder = 1 5/3 remainder =2

So NO FOOD

2.

n=4 n+1 =5 5/3 =2 4/3 =1

n=7 n+1=8 8/3=2 7/3 =1

Notice how the trend is every 3 for n. so it is working correctly

B
