I assume that a person (a student) having a bit of brain cells in his head, who is able to read and understand the problem,
can do the rest on his (or her) own . . .
If not, then write first line as
1 400 (the number of the first week and the amount)
Then write the second line as
2 410 The number of the second week and the allowance 400 + 10 = 410)
You will get the first two lines
1 400
2 410
Now, if you want to continue, write the 3-rd, the 4-th and so on lines,
by adding 10 to the number in the previous line.
Was it unclear to you before you got my response ?
