• 1)
  12,3,15,14,6,19,16,9,23,18,12,...
  15+4=19
  19+4=23
  23+4=27
  ans is 27
  OR
  12+3=15-0=15
  14+6=20-1=19
  16+9=25-2=23
  18+12=30-3=27
  
  SO ANS IS 27
  
  
  2)
  -15,-14,34,32,42,39,58,54,61
  I THINK QUESTION IS WRONG
  -15-(-14)=-15+14=-1
  34-32=2
  42-39=3
  58-54=4
  61-56=5
  SO ANS IS 56
  BUT I'M NOT CONFORM BRO

• ans 1. divide the series in group of three nd then subtracting 1st no wid 3rd no, we get 2nd digit as....
  12,3,15 :- 15 - 12 = 3-0=3
  14,6,9 :- 19 - 14 = 6-1=5
  16,9,23 :- 23 - 16 = 9-2=7
  18,12,x :- x - 18 = 12-3=9
  so x is 27. ans 27

• 1. divide the solution into 4 rows which contains 3 numbers in each.
  12, 3, 15
  14, 6, 19
  16, 9, 23
  18, 12, ?
  here observe 3rd column that
  15+4=19
  19+4=23

• (12,3,15)(14,6,19)(16,9,23)(18,12,x)
  1st term:12,12+2,14+2,16+2
  2nd:3,3*2,3*3,3*4
  3rd:15,15+4,19+4,23+4
  so Ans:27
