• For Ques 2 Answer is 11
  Write the series in the matrix format as given below.
  18 21 17 24
  24 27 23 30
  5 8 4 11
  Now see the pattern...18-1=17,21+3=24
  24-1=23,27+3=30
  5-1=4,8+3=11
  So the answer is 11

• 5) 7*7 = 49 and 49*2=98
  4*4=16 and 16*3=48
  3*3 = 9 and 9*4=36
  so next is
  5*5=25 and 25*5=125
  so last term is 125

• For 11 question..sorry the answer is -56 not -66..
  subtract the numbers...
  -15-(-14)=-1.
  34-32=2
  -42-(-39)=-3
  58-54=4
  -61-(-56)=-5..
  The answer is -56..

• 1) 156
  2) 1 [(24)4+1=5,(27)7+1=8,(23)3+1=4, same (30)0+1=1]
  3) 74 [83-9]
  4) 12 [1*3=3,2+8=10,3*4=12,4+8=12]
  5) 500 [25*(25-5)]
  6) 3 [make a group of 4{9,12,4,8}{12,15,5,9}{3,6,2,6}{6,9,3,7}

• explaination of quest.2-
  first term is 18..then see 4th term,which is= +3 of 18 that is 21.
  again see 7th term,which is= -4 of 3rd term that is 17.
  again see 10th term,which is= +7 of 4th term that is 24.
  if u will follow same rule(+3,-4,+7) for 2nd term and 3rd term u will get ans = 11.

• 7.add 1st two term =4 th term
  such as 1+1=2 ignore 3rd term i.e.1
  then 2+2=4
  3+3=6
  and which term ignored are 1,3,5
  that meanns the series will be like
  1,1,1,2,2,2,3,4,3,3,5,6,4,4,7,8
• 10 years agoHelpfull: Yes(3) No(2)
• 
  3)difference in term is
  100-98=2
  98-95=3
  95-90=5
  90-83=7
  2,3,5,7 all are prime number next prime number is 11
  so next term=83-11=72 ans

• For 10 question...
  -16/2=-8.
  -8/2=4...remove - sign.
  and 24/2=12.
  12/2=-6...add - sign.
  and -40/2=20...remove - sign..

• 11. diff of 1st two -14-(-15)= +1 , diff of 2nd two 32-34= -2,similarly diff of 3rd two=+3,diff of 4th two=-4, diff of 5th two=+5. so the no is = -61+5= -56

• 5.Ans is...........
  (7^2=49) so 49*2=98,
  (4^2=16) so 16*3=48,
  (3^2=9) so 9*4=36,
  (5^2=25) so 25*5=125
  so the next number in the series is 125

• 5) ans- 125
  reason:- if we make a group of 3 no.s i.e (49,7,98), (16,4,48) ,( 9,3,36) , (25,5, x) . here we need to find x.
  now if we look at the groups then we can see that , in each groups the 1st element is the multiple of last element i.e the 3rd element in each respective groups.
  ( 49,7,98) :- 49*2= 98
  (16,4,48):- 16*3=48
  (9,3,36) :- 9*4=36
  so in (25, 5, x) :- 25*5= 125. hence x is 125.
