Easy matrix question confusion

Write down the system of equations of when and a_{ij} = i + j for , , , , while b_{j} = j = 1, ,

Answer is:

2x_{1} + 3x_{2} + 4x_{3} = 1

3x1 + 4x_{2} + 5x_{3} = 2

4x_{1} + 5x_{2} + 6x_{3} = 3

Seems like an easy question but not really sure on what they're asking so any clarification will greatly help. Thanks!

Yes, to me it appears that this is no more than what you've already put down.

Sometimes the problems are intriguingly simple.
