To find the 20th term of a sequence, you need to identify the formula or pattern governing the sequence. For arithmetic sequences, you can use the formula ( a_n = a_1 + (n-1)d ), where ( a_n ) is the nth term, ( a_1 ) is the first term, ( n ) is the term number, and ( d ) is the common difference. For geometric sequences, the formula is ( a_n = a_1 \times r^{(n-1)} ), where ( r ) is the common ratio. Plug in the values to calculate the 20th term accordingly.

How do you work out the 20th term of a sequence?
To find the 20th term of a sequence, first identify the pattern or formula that defines the sequence. This could be an arithmetic sequence, where each term increases by a constant difference, or a geometric sequence, where each term is multiplied by a constant factor. Once the formula is established, substitute 20 into the formula to calculate the 20th term. If the sequence is defined recursively, apply the recursive relation to compute the 20th term based on the previous terms.
If the common difference in the arithmetic sequences for and the 20th term is 36 what is the first term?
In an arithmetic sequence, the nth term can be expressed as ( a_n = a + (n-1)d ), where ( a ) is the first term and ( d ) is the common difference. Given that the common difference ( d ) is 36 and the 20th term ( a_{20} = a + 19d ), we can set up the equation ( a + 19(36) = a + 684 ). To find the first term, we need additional information about the value of the 20th term; without that, we cannot determine the exact value of the first term ( a ).
Find the 20th term what sequence -6 -4 -2 0?
Increase of +220th term x 2 = 40(take away the first 4 terms)40 - (4 x 2) = 32By formula method:This is an arithmetic progression.First term is a = --6; common difference d = +2 the expected term n = 20By formula, tn = a + (n--1)dHence plugging, the required 20th term is --6 + 38 = 32

If the 20th term in a sequence is 50 what is the 21st term?
Oh, dude, you just add one to the term number to get the next term. So, if the 20th term is 50, the 21st term would be the 20th term plus the common difference of the sequence. It's like basic math, man.
How do you find the 20th term of the pattern 3 6 12 24?
The pattern given is a geometric sequence where each term is multiplied by 2 to get the next term. To find the 20th term, we can use the formula for the nth term of a geometric sequence: ( a_n = a_1 \cdot r^{(n-1)} ), where ( a_1 ) is the first term (3) and ( r ) is the common ratio (2). Thus, the 20th term is calculated as ( a_{20} = 3 \cdot 2^{19} ). Evaluating this gives ( a_{20} = 3 \cdot 524288 = 1572864 ).
If the common difference in the arithmetic sequences for and the 20th term is 36 what is the first term?
In an arithmetic sequence, the nth term can be expressed as ( a_n = a + (n-1)d ), where ( a ) is the first term and ( d ) is the common difference. Given that the common difference ( d ) is 36 and the 20th term ( a_{20} = a + 19d ), we can set up the equation ( a + 19(36) = a + 684 ). To find the first term, we need additional information about the value of the 20th term; without that, we cannot determine the exact value of the first term ( a ).
