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

no

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 is 60.

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

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.

It's an term which applies to the work of late 19th- and 20th-century philosophers.

First, you must find the difference between the numbers, for example if the numbers were 3, 5, 7, 9, 11 then it would be 2. All you have to do is find out the difference between 2 and the first number, which happens to be 3. So 3-2 equals 1.so the equation would be2n+1you always use n for the nth sequence term
