First, find the first term and the common difference of the arithmetic sequence. Substitute the values in the nth term of the explicit formula. Simplify the nth term mathematically to get the explicit formula.The explicit formulas can also be derived for the terms of the geometric progression ...
where Tn represents the nth term, a represents the first term, n represents the position of the term, and d represents the common difference between consecutive terms. Let's understand this formula in action with an example. Consider the arithmetic sequence 2, 5, 8, 11, 14. To find the ...
