11,17,27,38 what is the pattern

Question

Try to find the answer

Answer 1

11,17, 27, 41 has a parabolic pattern or sequence

y=2x^2+ 9 where x is the number of the term, "an"

with n=nth term

11= 2(1)^2 +9=2+9

17 =2(2)^2+9=8+9

27=2(3)^2 +9=18+9

41 =2(4)^2 +9=32+9

but your seqeunce has 38 not 41 as the 4th term.

there probably is another similar quadratic equation that fits that sequence
