SUMMARY

The function F(n) is defined recursively as F(1) = 2 and F(n) = F(n-1) + 1/2 for all integers n > 1. The correct calculation for F(101) involves recursively applying the function, leading to F(101) = F(100) + 1/2, rather than a direct arithmetic calculation. The final result for F(101) is 52, not 51, indicating a potential misinterpretation of the initial condition or a calculation error. Understanding the recursive nature of the function is crucial for arriving at the correct answer.

PREREQUISITES
  • Understanding of recursive functions
  • Basic arithmetic operations
  • Familiarity with mathematical notation
  • Ability to identify patterns in sequences
NEXT STEPS
  • Study recursive function definitions in mathematics
  • Practice calculating values of recursive sequences
  • Explore mathematical induction as a proof technique
  • Learn about sequences and series in algebra
USEFUL FOR

Students in mathematics, particularly those studying sequences and recursion, as well as educators looking for examples of recursive function problems.

Homework Statement



If F(1) = 2 and F(n) = F(n-1) + 1/2 for all integers n > 1, then F(101) = ?


Homework Equations





The Attempt at a Solution



F(101) = F(101-1) + 1/2 = 100 1/2

I know I'm missing something huge here because the answer in the book was 51. :-/ Thanks for your help.

Yes, you are missing something huge.
F(101) = F(101-1) + 1/2 = F(100) + 1/2, not 100 + 1/2.

Start by calculating F(2), F(3), and a few more to see if you can get an idea of what's happening here.
 
What is F(2)? F(3)? maybe you'll see a pattern... I would get 52 in the end though, are you sure it's not F(1)=1?
