Please help asap Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! If she collects the same amount of cans each week,
the numbers of cans collected after each week form an arithmetic sequence.
On week 2 she collected 126-88=38 cans.
During weeks 3 and 4, she also collected 38 cans each week,
for a total of 38+38=76 extra cans,
so by the end of week 4 she had 126+76=202 cans.
She must have also collected 76 cans during the first two weeks (week 1 and week 2),
but since she had 88 weeks in her collection by the end of week 2,
she must have started with 88-76=12 cans before she started her week 1 collection.
The number of cans in her collection after weeks is .
