F25 = 75,025 and F26 = 121,393 where Fn is the nth term in the Fibonacci sequence. Find F27.

MathMate
The Fibonacci sequence is such that each term is the sum of the two previous terms, assuming the first two terms are 1 and 1.
So F1=1
F2=1
F3=(F1+F2)=2
F4=(F2+F3) = 3
F5 = (F3+F4) = 2+3 = 5
...
F25 = 75,025
F26 = 121,393
F27= ?
