F 25 = 75,025 and F 26 = 121,393 where Fn is the nth term in the Fibonacci sequence. Find F27.

Answer 1

Each term of the Fibonacci sequence is obtained by adding the two previous terms.
For example, in the initial sequence,
1,1,2,3,5,8,13....75025,121393,....
F1=1
F2=1
F3=F1+F2=1+1=2
F4=F2+F3=1+2=3
F5=F3+F4=2+3=5
...
F23=28657
F24=46368
F25=F23+F24=28657+46468=75025
F26=F24+F25=46368+75025=121393
F27=?
