Identify the value of the missing term in each geometric sequence. 1.___,-32,16,-82.100,50,25,____3.-2,12,____,4324.-4,____,-64,2565.32,2,⅛,____
Answer (1)
Answer:1. -64 The sequence is -64, -32, 16, -8. The common ratio is \( \frac{-32}{-64} = \frac{1}{2} \).2. 12.5 The sequence is 100, 50, 25, 12.5. The common ratio is \( \frac{50}{100} = \frac{1}{2} \).3. 72 The sequence is -2, 12, 72, 432. The common ratio is \( \frac{12}{-2} = -6 \).4. -16 The sequence is -4, -16, -64, 256. The common ratio is \( \frac{-16}{-4} = 4 \).5. **⅛** The sequence is 32, 2, ⅛, 1/64. The common ratio is \( \frac{2}{32} = \frac{1}{16} \).
