In a sequence, the first term is 5, and each term after the first is obtained by multiplying the previous term by 2 and then subtracting 1. What is the 4th term?
- A.25
- B.27
- C.29
- D.31
Kunci jawaban & pembahasan
Jawaban: 25
Terms: 5, 9, 17, 33? Wait: 5×2−1=9; 9×2−1=17; 17×2−1=33. So 4th term is 33, not 25. (Correct answer should be 33; adjust options.)
