[@laurenemmett-turner8503]

i dont like the fact. that you go straight into the teaching i feel like you should give some background. Just my opinion.

[@MariosMathTutoring]

I appreciate your input and will consider that for new videos that I film and upload. Thank you Lauren.

Yeah i dont even know what is the difference between geometric sequence arthmetic sequence

how to work this one 5 , 10,17,26 find the other 3 what am I not understanding

[@nwryy9693]

What if the question asks us to find the first integer in the rth set where the geometric sequence is 1,2,4,8 ?

[@midoriorio7806]

It's 1, 0 is not an integer

[@mamood1783]

when u wish there was a easy tutorial for dummies like me
never gonna find one :(

[@banjotkohli7734]

Your explanation for why we use or why n-1 is there is not clear, can you please explain in some other way.

[@vister6757]

Because the first value i.e. 3 need not multiply by r. It only starts multiplying at the 2nd term, hence when you want to find the 3rd term u only multiply r twice instead of 3 times (r^2; r^(n-1) where n=3)

What about this One:
a5 = 567, r=3. Find a9.
But the Formula is : an=A1 × r^n-¹ ???

[@yilo8856]

Can I ask what if the missing is the ratio and n while the given is the sum the nth term and first term???? I need your reply asap plss reply😭🙏

hello sir im from Malaysia, i know too late to ask the answer for 12 terms , but is it correct the answer is 5/1024 😅
