Geometric Sequences: Find the first term and common ratio

In this video, we use the general equation for terms of a geometric sequence:

t_n = ar^(n-1)

to find the first term a, the common ratio r and the nth term of a geometric sequence for a known values of the third term (t_3 = 100) and 5th term (t_4 = 400).

Thanks for watching. Please give me a "thumbs up" if you have found this video helpful.

I apologise for the poor audio quality on this video. I was too close to the mic!

was very helpful I now understand something that previously took me around three hours to understand 😊

Brief, clean and so very eloquently explained, you have my thanks for your kindness of sharing this tutorial

[Carlvin-mc]

This is damn extremely detailed explanation, thanks 🙏

Tha best that I was in need of ....very simple steps..kudoos and thanks

[Pluneto]

thanks for the vid, cleared up a lot of things for me!

You explained something which was so hard for me to understand from my sir. Thank you so much

[pandesal]

Thank you so much! You are a really amazing teacher.

[DelMysthic_BLOG]

thankyou for your great explanation sir, but when you crossed out the zeros of 400 and 100.... should i crossed out mine like: 48 and 1536, should i cross out the 8 and 536...? to get 4 and 1?

I don't really understand can you make just 1 video for finding the first term of a geometric sequence please? Just like this for example: Find the first term of a geometric sequence whose fourth term is 1000 and whose common ratio is 5. Please ❤ Thank you

[innocentzimba]

The second nd fifth term of a geometric progression are 16 nd 2 respectively.
find
1 the common ratio nd the first term

my math book gave me eighth root 4, , should i leave the symbol

[keishabuenviaje]

omg! I was looking for this, finally found it! Thankyouu grade saver!

[bryanedwards]

Can you like mention where you got the numbers before you just write them down

[thecharmingandtalentedguyw]

This is pissing me off, every video covering this does low terms, ive got the 50th and 61 term and no clue how to find the first term once ive got the ratio hrheneb evegsioiskNsjiw
