nvm about the angles one. got that. but the first two...?

first one, keep doubling but switch the signs........? Next would be -64 and 128. I think. I dunno. Second.....halve the number you add each time. 32+16=48. 48+8=56. 56+4=60. 60+2=62. 62+1=63. Next are 63 1/2 and 63 3/4.

for the first one:
2, -4, 8, -16, 32, _-64_, 128
as you may notice, 2 (the first number) x -2 equals -4 (the 2nd); -4 x -2 = 8; etc. so then 32 x -2 = -64 and -64 x -2 = 128
for the second:
I honestly have no idea..sorry but I hope what I have for the first helps
