We double 1 to get 2 then take that result of 2 and apply double again to get 4 then take the 4 and double it to get 8 and so on. Students teachers parents and everyone can find solutions to their math problems instantly. Write this rule as a recursive formula.
We hit the seed value so we are done with the first phase.
Then a recursive formula for this sequence will be needed to compute all the previous terms and find the value of t n. In arithmetic sequences with common difference d the recursive formula is expressed as. While recursive sequences are easy to understand they are difficult to deal with in that in order to get say the thirty-nineth term in this sequence you would first have to find terms one through thirty-eight. The Fibonacci sequence is another classic example of recursion.
