Sum of first 52 elements=352849027131.
Observing the pattern of the given numbers, we conclude that T(n)=T(n-1)+T(n-2); where T(n) is the nth term of the given sequence of numbers. I used a computer program to generate few terms of this sequence and the sum till an arbitrary 'n'. The sums follow the pattern S(n)=T(n+2)-6; where S(n) is the sum of elements till n. Hence, by using the above pattern we can get sum of first 52 elements of the sequence. Here's the link to the program .

vikram sundesha  (8 years ago)

T(0)=1,T(1)=6
T(N+2)=T(N)+T(N+1) WHERE N>0
By using this we get the value
T(1)...+T(52)=352849027131
