i can't find these patterns.

my mom and dad tried to.

first problem
64,__,___,___,32

second problems
61,___, ___, ___, 81

2 answers

first: each blank decreases by 8 ( four decreases to 32 from 64, or 32/4)

second: four increases for a total increase of 20, so 20/4 is five increase in each blank.
I think I have an answer to both the first and second problem.
Problem 1-It appears you are subtracting 8 each time.
64-8=56
56-8=48
48-8=40
40-8=32
64,56,48,40,32

Problem 2-It appears you are adding 5 each time. 61+5=66
66+6=71
71+5=76
76+5=81
61,66,71,76,81
