4. The product of two consecutive numbers is 702.\

5. The sum of two numberes is 18. The difference between them is 2.

thanks!~

2. 4 and 8. (12+4)/2=8,8/2=4
3. 4/3 and 20/3. 8/(5+1)=4/3,4/3*5=20/3
4. 26 and 27. x(x+1)=702,x=26,26+1=27
5. 10 and 8 (18+2)/2=10,10-2=8

2. x+y=12 x-y=4
so
x=8, y=4
3.x+y=8,x=5y
so
x=20/3 y=4/3
4. xy=702 x+1=y
so x=26 y=27
5. x+y=18 x-y=2
so x=10 y=8

a clerical error
