Increase of +2
20th term x 2 = 40
(take away the first 4 terms)
40 - (4 x 2) = 32
By formula method:
This is an arithmetic progression.
First term is a = --6; common difference d = +2 the expected term n = 20
By formula, tn = a + (n--1)d
Hence plugging, the required 20th term is --6 + 38 = 32

What is the 20th term of the following sequence-6 -4 -2 0?
As can be seen, each succesive term is 2 greater than the last. We can write a rule to calculate the nth term. Here the rule equals 2n - 8. So the 20th term = (2 * 20) - 8 = 32.
Explain how to find the terms of Fibonacci sequence?
If the Fibonacci sequence is denoted by F(n), where n is the first term in the sequence then the following equation obtains for n = 0.
What sequence is formed by subtracting each term of a sequence from the next term?
It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b
A sequence formed by subtracting each term of sequence from next term is?
If the first two numbers are 0, 1 or -1 (not both zero) then you get an alternating Fibonacci sequence.
What is the pattern for 0 0 1 3 6?
The pattern for the sequence 0 0 1 3 6 is that each term is obtained by adding the previous term multiplied by its position in the sequence (starting from 1). In other words, the nth term is given by n*(n-1)/2.
What are the first four terms of a sequence and what term number is -32 when the nth term is 8 -2n?
If the nth term is 8 -2n then the 1st four terms are 6, 4, 2, 0 and -32 is the 20th term number

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

What is the pattern for 0 0 1 3 6?
The pattern for the sequence 0 0 1 3 6 is that each term is obtained by adding the previous term multiplied by its position in the sequence (starting from 1). In other words, the nth term is given by n*(n-1)/2.

Find nth term for sequence 0 5 10 15 20 25 30 35?
This is an arithmetic progression. In general, If an A.P. has a first term 'a', and a common difference 'd' then the nth term is a + (n - 1)d. In the sequence shown in the question, the first term is 0 and the common difference is 5, therefore the nth term is, 0 + (n - 1)5. This can be rearranged to read : 5(n - 1) For example : the 7th term is 30 : 5(7 - 1) = 5 x 6 = 30.
What is the nth term for 4 2 0 -2?
To work out the equation of a sequence, you should first look at the differences in the sequence. In this case, the differences between the numbers are -2, -2, -2. Thus the equation for the sequence is x-2n To work out x, you need to find what the "0th term" would be, or the term that would come before 4. In this case, it would be 4+2=6. Therefore, the equation for the nth term is 6-2n
