A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a constant ratio. These sequences appear often in math problems involving growth, decay, finance, and patterns.
We’ll explore common types of geometric sequence problems and walk through their step-by-step solutions to help you understand the concepts and apply them with confidence.
The second term of a geometric sequence is 
, and the fifth term is 
. Determine the sequence.

I get it somehow, there are others who are unfamiliar and I have a hard time with it but it’s okay that I get it.
Thanks for sharing your thoughts! It’s completely normal to find some parts unfamiliar or more difficult than others. The important thing is that you’re making progress and understanding more as you practise. Keep going! 😊
At least I understood some of it, but there are others that I’m confused about and have a hard time understanding, but I get it.
Thanks for sharing! It’s great that you’ve understood some of it already. Don’t worry if a few parts are still confusing — keep practising and take your time with the trickier sections. You’ll get there! 😊
The lesson was a little difficult for me, especially the word problems, but the examples helped me understand it better.
Thanks for your feedback! Word problems can definitely be tricky, so we’re glad the examples helped make the lesson clearer. Keep practising — it gets easier with time! 😊
