Given two terms find the nth term of a geometric sequence

Показать описание
👉 Learn how to find the nth term of a geometric sequence. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. A geometric sequence is a sequence in which each term of the sequence is obtained by multiplying/dividing by a common value, called the common ratio, to the preceding term.

The formula for the nth term of a geometric sequence is given by An = ar^(n - 1), where a is the first term, n is the term number and r is the common ratio. We can obtain the common ratio by dividing a term by the preceding term or if the known terms are not consecutive, we can obtain the common ratio by taking the nth root of the quotient of the two terms, where the n in the nth root is the difference of their term numbers. Plugging the required values into the formula, we can obtain the required nth term of the geometric sequence.

after slowing this video down, and doing the math homework given to me following your steps, I've learned more in 15 minutes of you video compared to 3 whole bells of algebra. Thanks man.

I've been teaching for 20+ yrs and LOVE using your videos. Even when you go too fast, we can stop the show, rewind and reuse. My Army girl is now using you to increase score to promote. THANKS!

Sir, thank you. I’ve learned more in these 9 minutes than the whole year in my math class.

Mr Brian, You could have found a14 in another way too. Since you found r=1/2, you can use the usual formula, a14= a1* r^13, , to get the final answer, 1000/8192 = 0.1221

Wish my math teacher was this fun to learn with. A video does better than my current maths teacher

Thank you so much! Doing math homework used to mean staying up all night crying and praying that I would do okay on the text, but thanks to your videos, I've gone from 60/70s to 90s in college pre-calc.

I'm getting ready for an exam for my precalc class that I haven't been able to attend for 3 weeks, so these videos are saving me. Thank you.
