- To refer to any term of a sequence, we use the un u n notation, where n n indicates the term we're referring to. For instance, if we're dealing with the sequence 3, 7, 11, 15, 19, 23, … 3, 7, 11, 15, 19, 23, … we would refer to the first, second and third terms as: u1 = 3 u 1 = 3 u2 = 7 u 2 = 7 u3 = 11 u 3 = 11

To work out the term to term rule, give the starting number of the sequence and then describe the pattern of the numbers. The first number is 3. The term to term rule is 'add 4'. Once the...
The nth term refers to the position of a term in a sequence. For example the first term has n=1, the second term has n=2, the 10th term has n=10 and so on. The ‘n’ stands for its number in the sequence. We can make a sequence using the nth term by substituting different values for the term number(n).
When the nth term is known, it can be used to work out specific terms in a sequence. For example, the 50th term can be calculated without calculating the first 49 terms, which would take a long...

Mar 20, 2023 · How do I use the n th term formula for a sequence? nth term formulae can be given as algebraic expressions in terms of n that take positive integer values of n only for example, To find the value of the first term, substitute n = 1 into the formula; To find the value of the second term, substitute n = 2 into the formula, and so on
This online tool can help you find n th term and the sum of the first n terms of an arithmetic progression. Also, this calculator can be used to solve much more complicated problems. For example, the calculator can find the common difference ($d$) if $a_5 = 19 $ and $S_7 = 105$.
