Hi sir how about sir if the given values are a3=8 and a8=1/4. What is the common difference and the first term?

Hi sir, how to find the common ratio if the only given is the first term which is 3 and the sum of 6 terms of the geometric sequence is - 63??

Thank you sir! Helpful talaga yung mga videos mo.

nichimarie

Thank u po! Laking tulong lalo na sa modular na tulad ko po hehe

Thank you sir for the tutorial it helps me a lot.

Hello Mr. How could I find the first term of a geometric sequence when the sixth term is -1280 and the ratio is -4/5? Thanks for the help

nakatulong po siya sa module ko, Kasi meron po kaming ganyang lesson pero Hindi tinuro sa module. Salamat po Ng marami godbless po.

Hi, I am very late watching the tutorial. thank for your brief explanation and I look forward to you doing more videos on arithmetic sequence and the sum of both arithmetic and geometric series.
Below are my answers:
#1. a1= 0.5 or 1/2
#2. r= 3
#3. a1= 0.375
#4 I need help 😫 on that???
thank you and hope you respond as soon as possible.

Hello Mr. How pls help me with this..
THE THIRD AND EIGHT TERM OF A GEOMETRIC SEQUENCE ARE 8 AND 1/4 RESPECTIVELY. WHAT IS THE FIRST TERM AND THE COMMON RATIO OF THE SEQUENCE?

ryanvillamala

Sir can u Identify whats wrong with my solution so A1=1/2 and A5=2048
I used the r n-m = An / Am but i got
r=256 which is wrong

heyboss

The third and eighth term of a geometric sequence are 8 and
¼ respectively. What is the first term and and common ratio of the sequence?

Please help me🥺 thanks

meicalheirix

sir, I have a question I have problems with
GP
the 6th term is eight times the 3rd term and the sum of the 7th and 8th term is 192. Determine the common ratio, first term, and the sum of the 5th to 11th terms(inclusive).
CAN YOU PLS

patrenablair

sir, what is m in the alternatibe solution for common ratio po?

jam

sir, how to get the first term if r= 1/4 and the 8th term is also 1/4??

schatz

Good evening, sir. Ask ko lang po if there's no sequence given and pattern lang po ang ibinigay, paano po ito iso-solve? Thank you po.

pastxlbruhh_

Sir, what is the equation for solving for k for k-3, k+1 and 4k-2. Hindi ko po siya makuha. Thanks po.
