diff. 46-1,163-46,388-163,757-388
45 ,117, 225 ,369 ,
again diff 117-45=72, 225-117=108,369-225=144
so we have 72, 108, 144
which are 6*12 ,9*12,12*12
so next will be 15*12=180
second series will be 45, 117, 225,369,549(180+369)
final series 1, 46 ,163,388,757,(757+549=1306)

1) 39 - 41 = 2;
25 - 41 = -16;
26 - 25 = 1 ; 27 - 26 =1;
38 - 27 = 11;
again the pattern is repeat
40 - 38 =2;
24 - 40 = -16;
25 -24 = 1; 26 - 25 =1;
x - 26 =11
x= 26 + 11 = 37
So 37 is our next number
