Answer 1

b)

2¹ = 2

2³ = 8 = 2 × 4

q = 4

S8 = 4 × (4⁸ -1) / 4 - 1

S8 = 4 × (65536 - 1) / 3

S8 = 4 × 65535 / 3

S8 = 4 × 21845

S8 = 87380

2)

q = 5

S6 = 5 × (5⁶ - 1) / 5 - 1

S6 = 5 × 15625 - 1 / 4

S6 = 5 × 15624 / 4

S6 = 5 × 3906

S6 = 19530

3)

q = 4

S7 = 4 × (4⁷ - 1) / 4 - 1

S7 = 4 × 16384 - 1 / 3

S7 = 4 × 16383 / 3

S7 = 4 × 5461

S7 = 21844
