Need badly will give

list the next three terms in the following sequence:
1, 2, 4, 8, 16,

a. 48, 80, 128
b. 64, 96, 160
c. 64, 128, 256
d. 46, 92, 184

The first number multiplied by two is 2. Two multiplied by two is four. Four multiplied by two is eight. Eight multiplied by two is 16and so on. So in this case, the answer would be C because 32*2=64, 64*2=128, 128*2=256. 

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
