They are 14, 42, 126, 378 and 1134.
A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
FALSE (Apex)
Ratio
It is 4374
The 99th term would be a times r to the 98th power ,where a is the first term and r is the common ratio of the terms.
Yes, that's what a geometric sequence is about.
A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
yes
a, ar, ar^2 and ar^3 where a and r are constants.
A static sequence: for example a geometric sequence with common ratio = 1.
FALSE (Apex)
No, they do not. If the first term is negative, they always decrease.
Ratio
It is 4374
The terms are: 4, 8 and 16
a+a*r+a*r^2+...+a*r^n a = first number r = ratio n = "number of terms"-1
un = u0*rn for n = 1,2,3, ... where r is the constant multiple.
