What is the common ratio for the following sequence 648 - 108 - 18 - 3?
The "common ratio" of a geometric series is any of the numbers, divided by the previous number.If in all cases you get the same ratio (the same result of a division), then you have a common ratio. If the division gives you different numbers, then there is no common ratio.
What is the rule for the sequence of 6 12 18 24?
t(n) = 6*n where n = 1, 2, 3, etc
What is the most common denominator of 18 and 81?
There can be no greatest common denominator. If you have a set a numbers whose least common denominator is L then 2*L, 3*L, … are all common denominators. There is no end to that sequence and so no greatest.
How do you factor p2-6p-18?
You have to use the quadratic formula: p=(6±√(36+72))/2 p=(6±√108)/2 p=3±3√3
How do you solve -10b squared -27b - 18 equals 0 using the quadratic formula?
Divide all terms by -1 so that:- 10b2+27b+18 = 0 (5b+6)(2b+3) = 0 So: b = -6/5 or b = -3/2
What iis the 15th term of this sequence 22 18 14 10 6?
-34 would be the 15th term.
What is the formula for the geometric sequence 2 6 18 54 ...?
a(n) = a(1) x r^n-1 In this case a(1) is 2 and r is 3 That makes the formula a(n) = 2 x 3^n-1
What is the r value of the following geometric sequence -81 54 -36 12?
This is not a geometric series since -18/54 is not the same as -36/12
What is the r value of the following sequence 6 -18 54 -162?
To find the common ration in a geometric sequence, divide one term by its preceding term: r = -18 ÷ 6 = -3 r = 54 ÷ -18 = -3 r = -162 ÷ 54 = -3
What is the geometric mean of 18 and 54?
The geometric mean of 18 and 54 is 31.176914
What is the geometric mean of 18 and 2?
The Geometric mean of 18 and 2 is 6.
