t(1) = a = 54
t(4) = a*r^3 = 2
t(4)/t(1) = r^3 = 2/54 = 1/27 and so r = 1/3
Then sum to infinity = a/(1 - r) = 54/(1 - 1/3) = 54/(2/3) = 81.
It could be -3 or +3.
The Fourth Triangular Number is 10.
One fourth of a circle is 90 degrees.
the origin is the point in the graph that can be fourth vertex
One fourth of 90o = 90/4 = 22.5o
It could be -3 or +3.
1 and 1/2.

Well they all have quarters in them... But really they represent the decimals 8.25, 6.5 and 2.75 respectively.
the series can be 1,-4,16,-64
If there are only k numbers x(1),x(2)....,x(k), the geometric mean is the kth root of the product of these k numbers. Example: find the geometric mean of 4,3,7,8 We want the fourth root of 4 x 3 x 7 x 8 = 672 =(672)^(1/4) = 5.09146 is the geometric mean. The geometric mean is normally defined only for a set of positive numbers.
2+6+10+14 = 32 in the fourth level with s,p,d,f sub-levels (2, 6, 10, 14 electrons in each respectively)
Well, honey, if the first term is 7 and the common ratio is 1.1, all you gotta do is multiply 7 by 1.1 three times to find the fourth term. So, 7 x 1.1 x 1.1 x 1.1 equals 9.697. So, darling, the fourth term of this geometric sequence is 9.697.
You multiply each of the numbers together and then take the nth principal root, where n is the number of values multiplied together. So Geometric Mean (2, 3, 4, 5) = fourth root of (2*3*4*5) = 120 = 3.31 (approx).
According to the genealogical records in Genesis 5 and 9 the fourth oldest man would be Adam at 930 years. (Genesis 5:5) This is after Methusaleh at 969, Jared at 962 and Noah at 950 respectively..
50 cents, 25 cents, and 10 cents respectively.
The highest occupied energy level in potassium is the fourth energy level because potassium has 19 electrons, occupying the first three energy levels (with 2, 8, and 8 electrons, respectively) and the remaining electron is in the fourth energy level.
