What is the 7th term of the given Geometric progression?
1, 2, 4, 8, ____
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 64
In a geometric progression each term is the previous one multiplied by the common ratio \(r\), so the nth term is \(a r^{\,n-1}\).
Each term is double the one before it: first term \(a=1\), common ratio \(r=2\)
7th term, with \(n=7\): \(ar^{6}=1\times2^{6}=64\)
