WebEach operation does the opposite of its inverse. The idea is the same in trigonometry. Inverse trig functions do the opposite of the “regular” trig functions. For example: Inverse sine. ( sin − 1) (\sin^ {-1}) (sin−1) left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis. does the opposite of the sine. WebAnswer. We know that if the common ratio, 𝑟, satisfies 𝑟 < 1, then the sum of an infinite geometric sequence with first term 𝑇 is 𝑆 = 𝑇 1 − 𝑟. ∞. We can see that the first term is 1 3 2, so we will need to calculate the common ratio, 𝑟. We find this by dividing a term by the term that precedes it, so we will use the ...

WebJul 8, 2015 · 3 Answers Sorted by: 1 We have that 162 = a 1 r 4 and − 4374 = a 1 r 7 by the formula a n = a 1 r n − 1. Then solving for a 1 in both equations and setting them equal to one another, 162 r 4 = − 4374 r 7 You can then solve for r (your common ratio), and subsequently a 1 (your first term). You then have all of the information you need. Share Cite WebBecause a geometric sequence is an exponential function whose domain is the set of positive integers, and the common ratio is the base of the function, we can write explicit formulas that allow us to find particular terms. an = a1rn−1 a n = a 1 r n − 1.
