Answer:I think the question is wrongStep-by-step explanation:I donow
2nd sequence is not in GP. So nth term and n can not be determined.
Step-by-step explanation:
nth term of a sequence in geometric progression is calculated as:
where
a→ first term in the sequence
r→ common ratio
n→ number of terms in the sequence
For a sequence to be in geometric progression, the consecutive terms should have common ratio.
i.e the quotient of
In sequence one,
But in sequence two,
Therefore the second sequence is not in GP and hence the value of nth term and the number of terms can not be calculated.
