Answer 1

c) b₁ = 3 ; q = 2 =>

b₂=b₁q = 3 x 2 = 6

b₃ = b₂q = 6 x 2 = 12

b₄ = b₃q = 12 x 2 = 24

b₅ = b₄q = 24 x 2 = 48

f) b₂ = 32 ; b₅ = 4 => b₅ = b₂q³ => q³ = b₅/b₂ = 4/32 = 1/8 => q = 1/2

b₁ = b₂/q = 32/1/2 = 32 x 2 = 64

b₃ = b2 q = 32 x 1/2 = 16

b₄ = b₃q = 16 x 1/2 = 8

b₅ = b₄q = 8 x 1/2 =4
