23 38 45 64 67
since there is no continuous relation between these terms. hence
difference between 1st and 3rd term i.e 23 and 45 is=22
again, difference between 2nd and 4th i.e 23 and 64=26
again,between 3rd and 5th is i.e 45 and 67 is 22
hence the next difference should be 26.
therefore,the next term is=64+26
=90
hence ans=90

23,38,45,64,67, 90
because
difference between 23 & 38 =15
difference between 38 & 45 =7
difference between 45 & 64 =19
difference between 64 & 67 =3
so alternate increase +4 and decrease -4
then the next number is +4 means 19+4=23
so 67+23=90

ans is 90
