• 12.) the sequence is a mixture of multiplication & addition.
  1st,4th,7th & 10th terms are written in ascending order as 1,2,3,4.
  then 1st term*2nd term=3rd term i.e 1*3=3
  4th + 5th =6th i.e. 2+8=10
  again, 7th*8th=9th i.e. 3*4=12
  and 10th term + 11th term =ans i.e. 4+8=12.
  
  therefore the ans will be 12.

• 2) given series is wrong
  correct series is 4,2,-4,-8,32,26,-156,?
  
  for this take two numbers at a time and calculate differences
  4-2=2;
  -4-(-8)=4;
  32-26=6;
  -156-(x)=8
  therefore x=-156-8 become x=-164;
  Answer is -164

• 6) group them as a group of 4: 1,1,1,2 : 2,2,3,4 : 3,3,5,6 :4,?
  in each group 1st and 2nd term is an addition of 1 to the corresponding position in the previous group and 2nd and 3rd elements are an addition of 2 to its corresponding position in the previous group.
  eg: in the 2nd group
  1+1,1+1,1+2,2+2 = 2,2,3,4
