I am trying to help a 5th grader with her homework and I am having trouble with number patterns.

Just keep subtracting 8 to get the next number. It's a simple arithmetic sequence.

First 64-32 = 32. So the 3 steps must move a total of 32
The middle one would be half that distance, or 16. 32 + 16 = 48
64, ___, 48, ___, 32
The other ones would be half that distance between them, or 8
32 + 8 = 40
48 + 8 = 56
64, 56, 48, 40, 32
(The technical answer is that it could be ANYTHING. This is mathematically true, but the teacher would probably mark that wrong just because it is the smart-alec answer. If you want more info, let me know)

64, 56, 48, 40, 32
That would be my best guess, based on the information. Just divide the range of 32 to 64 into 4 segments:
(64-32) / 4 = 32 / 4 = 8
So 8 separates each segment.

because I was a math major the common number that they have together is 8 so the correct answer is 64,56,48,40,32. this represents the times table of 8 as we know it:
8 x 1 = 8
8 x 2 = 16
8 x 3 = 24
8 x 4 = 32
8 x 5 = 40
8 x 6 = 48
8 x 7 = 56
8 x 8 = 64
8 x 9 = 72
8 x 10 = 80
Good luck.
Vote for me, please.

an = a1 + (n - 1)d
32 = a1 + (5 - 1)d
32 = a1 + 4d
a1 = -4d + 32
64 = -4d + 32
32 = -4d
d = -8
The pattern is
an = 64 - 8(n - 1)
a(2) = 64 - 8(2 - 1)
a(2) = 64 - 8(1)
a(2) = 64 - 8
a(2) = 56
a(3) = 64 - 8(3 - 1)
a(3) = 64 - 8(2)
a(3) = 64 - 16
a(3) = 48
a(4) = 64 - 8(4 - 1)
a(4) = 64 - 8(3)
a(4) = 64 - 24
a(4) = 40
ANS : 56, 48, 40

Isn't it as simple as
