• a=1
  b=6
  3rd term=1+6=a+b
  4th term= 1+6+6=a+2b
  5th term= a+3b
  .
  .
  .
  52nd term= a+48b=1+48*6=289
  sum=52(1+289)/2=7540

• i think in a fibo series sum of Nth no is = (N+2)th term - 2nd term
  so 54rth term - 6(which is second term)
  but it is hard for me to find 54rth term. i will calculate it mannualy by c compiler but if some one have a trick for calculating Nth term then post it here........
