Sum of the first n terms in a Fibonacci sequence is [unparseable or potentially dangerous latex formula], where [unparseable or potentially dangerous latex formula] is the nth term of the given sequence, and [unparseable or potentially dangerous latex formula] is the nth true Fibonacci number (1,1,2,3,5,8,13,...) which 1,1,2 being [unparseable or potentially dangerous latex formula]. 0 is [unparseable or potentially dangerous latex formula].
Therefore, your sum is [unparseable or potentially dangerous latex formula].
