Five students sit around a circular table. Their chairs are numbered in order from 1 through 5. Abby sits next to both Ben and Colin. Dalia sits next to both Ben and Sarah. The numbers on Abby's and Colin's chairs add up to 6. Who sits in the chair. Please show work.

Abby sits in chair 5, because one beside her would be 1 and that belongs to Colin because the two add up to 6. Thus, Ben sits in seat 4. Dalia sits between ben and sarah, placing Dalia at seat 3 and Sarah at seat 2.

The list goes as follows:
1- Colin
2- Sarah
3- Dalia
4- Ben
5- Abby
