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.
no
The 20th Fibonacci number in the sequence is 6,765.
The sequence is Un = 19 - 3n so the 20th term is 19 - 3*20 = 19 - 60 = -41
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.
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.
20th term = 20*(20+1)/2
It is 60.
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.

no
The sequence is Un = 19 - 3n so the 20th term is 19 - 3*20 = 19 - 60 = -41
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 nth term is 8 -2n then the 1st four terms are 6, 4, 2, 0 and -32 is the 20th term number
Find the formula of it.
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.
Because that is how it is defined and derived.
It's an term which applies to the work of late 19th- and 20th-century philosophers.
