grade 11 math word problem?
If Bonnie is away from Clyde for n consecutive days, then the amount of heartache claude feels is given by h(n)=(2n+1)^3.
a)if Bonnie is absent, by how much does Clyde's pain increase between day n and day n+1?
b)how much more pain will he feel on day 6 than on day 5?
I now the answer to a is24n^2+48n+26
I know the answer to b is 866
Update:why did you factor out the 2?

a =>
[2(n+1)+1]^3 - [2n+1]^3
as pain is function of number of days
replace n with 5 in result obtained for a
