General term of a geometric sequence
WebJan 24, 2024 · To find any general term in the sequence, use the general term formula which is {eq}x_n = a + d(n-1) {/eq} where {eq}x_n {/eq} is the value of the nth term, a is the starting number, d is the ... WebAnd one way to think about it is that this function, G, defines a sequence where N is the term of the sequence. So for example, we could say this is the same thing as the sequence where the first term is 168, second term is 84, third term is 42, and fourth term is 21, and we keep going on, and on, and on.
General term of a geometric sequence
Did you know?
WebThe terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. For instance, if the first term of a geometric sequence is a1 = −2 a 1 = − 2 and the common ratio is r= 4 r = 4, we can find subsequent terms by multiplying −2⋅4 − 2 ⋅ 4 to get −8 − 8 then multiplying ... WebA geometric sequence is a sequence in which the ratio between any two consecutive terms is a constant. The constant ratio between two consecutive terms is called the …
