Mar 15, 2016 · Using the geometric sequence of numbers 1, 3, 9, 27, … what is r, the ratio between 2 consecutive terms?

It enters the main sequence fusing Hydrogen into Helium. If the star is less than eight solar masses it will stay in the main sequence for billions of years. Eventually the supply of Hydrogen in the core runs …

Feb 3, 2018 · How was this answer achieved in this geometric sequence question? Find Tn of the geometric sequence 1, 1.4, 1/16, 1/64

The formula for a term of this last sequence can be written: a_n = floor (1/2 (sqrt (8 (n-1)+1)-1)) color (white) (a_n) = floor (1/2 (sqrt (8n-7)-1)) So the formula for the previous sequence can be written: …

A finite sequence does not determine a unique formula. The above formula is the simplest polynomial function that matches the given values.

Nov 26, 2017 · This is the condition that #a_n# be a Cauchy sequence. So if the set of numbers is closed under Cauchy sequences then the limit exists. Such is true of the set of Real numbers, so the …

Jul 3, 2018 · 1) The general form of for the nth of a geometric sequence with first term a1, common ratio between all terms r is given by an = a1(r)n−1 Given a1 = 2,r = 4, we plug these values into the above …

Jun 20, 2016 · Of sequence and series the latter is the hardest (adding up a sequence). For this the only real solution is to find a guide/book with lots of examples and practice questions (with answers).

Do you mean a geometric sequence ? If so, it's an infinite list of numbers x_ {0},x_ {1},x_ {2},x_ {3},\ldots with the property that x_ {k+1}=r x_ {k} for some number r (and for all integers k\geq 0). Because of …

Find the common ratio, r, in the following geometric sequence. 2, 6, 18, 54, … 3 -3 4 9 ?
