12.1.26, 59c, & 61

12.1.26
for this problem, i noticed that they alternate changing by 13 and -7, the signs change, and a1=8 but i didn't know how to put that into an equation. all i know is that 8*(-1)^n is in there. how do i finish it?

12.1.59c
the book gave an explanation for the pattern but it didn't make any sense to me. help?

12.1.60
is there a typo? does it mean to say integers less than one or equal to 15? and if so, what is the question asking because that's confusing too

thanks, monica

for 59 there is a typo for the explanation, the nth partial sum is really a sub n+2 -1, if you line up your fibonnaci numbers and your new pattern it is very easy to see.
