difference from 1 and 2 = 4
difference from 2 and 3 = 9
difference from 3 and 4 = 16
Do you see anything special in the differences?
firs form two columsn
2 5 4
3 14 9
4 30 16
if you take the difference between the number of nickels for consecutive days you get the sequence 4,9,16,...
that is, day2 nickels - day1 nickels = 4
day3 nickels - day2 nickels = 9
day4 nickels - day3 nickels = 16
notice that these are perfect squares, so we could continue that difference column as 4,9,16,25,36,49 ....
and build up our chart by working backwards.
the next row would be
5 55 25 and then
6 91 36 ... continue to row 10
there are more sophisticated ways to do this, but not suitable for grade 6 math
(I noticed that the third difference column gives me a constant of 2, suggesting that a cubic expression can be found for 1,5,14,30,...
but that would be beyond grade 6 math)
first night=1 nickle
second night=5 nickles
third night=14 nickles
fourth night=30 nickles
there for every day the mom gives the child two more nickles plus what she got the day before, so the next night the child should receive 54 nickles. I'm prety sure.
