This video teaches all you need to know about Geometric Progressions, and how to solve questions on geometric progressions and sequences. MASTER GEOMETRIC PROGRESSIONS IN UNDER 30 MINUTES!!! The examples are taken from the New General Mathematics for Senior Secondary Schools, book 2 (SS2) - Exercise 18c (Page 208). • 0:00 - Introduction of terms and concepts • 02:49 - QUESTION 3: Write down the common ratios of the following GPs • a) 64, 32, 16, 8, ... • b) 0.05, 0.5, 5, 50, ... • c) -2, -3, -4.5, -6.75, ... • 04:05 - QUESTION 5: Find the nth term of the GPs with the following parameters • a) First term = 5, common ratio = 2 • b) First term = 1/4, common ratio = 1/2 • 07:53 - QUESTION 7: Find the common ratio and the number of terms for the given GPs • a) 3, 6, ..., 768 • b) 54, 18, ..., 2/27 • c) 10/7, 1, ..., 343/1000 • 16:06 - QUESTION 9: Three numbers form a GP. If the first and third numbers are 5 and 245 respectively, find the two possible values for the middle number. • 17:44 - QUESTION 11: Find the number of terms in a GP given that its first and last terms are (16/3)k and (243/256)k respectively and that its common difference is 3/4. • Thanks for watching. • It would mean a lot to me if you subscribed 😊 • / @nonsomaths • For inquiries, please contact me through https://wa.me/message/OC7PRKG76VNFO1 • #maths #geometricprogression #mathexams
