11,17,23,31
17-11=6 step 1
23-17=6 step 2
31-23=8 step 3
here step 2-step1 =0
step3-step2=2
then step4-step3=4
add 12 to 31 then we get 43 exactly....

consider the series 11,17,23,31
in between these two prime numbers there is one prime number missing so the series would be 11,13,17,19,23,29,31,37,43 so skip 37 n answer is 43
