WILL MEDAL. a collection of books is set up into 34 rows. The first row has 96 books, and each row after that one has 2 less books then the preceding row. How many books are in the 17th row?
I would go with an equation like 96-2(y-1)=amount of books y=rows it's y-1 because 2 rows, should only have 2 less, not 4.
maybe binomial theorem
i think it is either 164 or 255
@sar12389 There is no way the 17th row will have more books than the first.
96-2(y-1)=amount of books y=rows plug into that equation^
y=17 in this case
i read the question wrong then. The answer would be 64
the possible answers are 255, 164, 128, or 64
It's 64. Even by logic from those choices..lol.
My equation has that at 64, so corret
*correct
96-2(n-1) n=17 96 - 32=64
