Abstract: Dougall's 5F4 summation formula plays an important role in the theory of special functions, and its various applications have been widely discussed. Using Dougall's 5F4 summation formula, we derive some new summation formulas, from which new Ramanujan type series for 1/π and 1/π2 are obtained.

Key words: gamma function, hypergeometric functions, Dougall's 5F4 summation, Ramanujan type series
