the (n-1)th term plus the (n-2)th term.

This is the Fibonacci sequence, where the number is the sum of the two preceding numbers. The nth term is the (n-1)th term added to (n-2)th term

Let n (i) = the term number of each term in the sequence., with (i) going from 1-6 E.g term number 1 (n (1) ) is 3. n(2)= -7 etc... Therefore n(i) for odd terms in the sequence is n (i)= (n (i -2)th term +1). For even terms in the sequence, n(i)= (n (i - 2)th term -3).

The nth term of a arithmetic sequence is given by: a{n} = a{1} + (n - 1)d → a{5} = a{1} + (5 - 1) × 3 → a{5} = 4 + 4 × 3 = 16.

1. Each term is half the previous term.

1 - 2 - 4 - 8 - 16 - 32 - 64 the sequence doubles

The 8th term is 64. The sequence is the squares of the counting numbers. The nth term is given by t(n) = nÂ².

1, 16, 81, 256 14641 is the 11th term.

the series can be 1,-4,16,-64

1, 4,9, 16, 25, 36,49 this is the next three sequence po

The sequence is a geometric progression.Here, first term(a) = 1 and common multiple(r) = 4.nth term of G.P. is given by an = arn-1If we put n = 5, then a5 = 1x44 = 256.So next term in the sequence is 256.

The (n)th term = the (n - 1)th term + (2n + 1)

2 + ((6 + 2 * (n - 1) * (n - 1))

multiply the previos term by 4, you'll get 256x4

You mean what IS a geometric sequence? It's when the ratio of the terms is constant, meaning: 1, 2, 4, 8, 16... The ratio of one term to the term directly following it is always 1:2, or .5. So like, instead of an arithmetic sequence, where you're adding a specific amount each time, in a geometric sequence, you're multiplying by that term.

The general term for the sequence 0, 1, 1, 2, 2, 3, 3 is infinite sequence.

If the first two numbers are 0, 1 or -1 (not both zero) then you get an alternating Fibonacci sequence.

Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}

The nth term of the sequence is 2n + 1.

This is a sequence based on the squares of numbers (positive integers) but starting with the square of 2. Under normal circumstances the sequence formula would be n2 but as the first term is 4, the sequence formula becomes, (n + 1)2. Check : the third term is (3 + 1)2 = 42 = 16

The sequence S = 2, 2, 4, 6, 10, 16, 26, ... is the Fibonacci sequence multiplied by 2. Like the Fibonacci sequence, each term is found by adding the two previous terms, so Sn = Sn-1 + Sn-2.

36 Seems like: 1 4 9 16 25 is squared sequence: 1 2 3 4 5 So 6 squared will be 36.

While there are not enough numbers to fully clarify the nth term of the sequence, according to the sequence so far it appears that the nth term is equal to n4. Therefore, the next number will equal 44 = 256
