1)-3,6,1,-2,4,-1,21,2,-3,? may be series wrong somwehere

2) 1/2, 1/2, 1/4, 1/6, 1/8, 1/16? @@@@@@@@@ 1/12 1/18 1/24 1/64 [mul 2 ,3,4 to denominators]

3)22, 19.5, 21.45, 33, 26, 15, -1, ? question wrong it seems, It should be 22,19.5,21.45,33,30.5,33.55,44,41.5,?@@@@@@@@@@ 45.65

4)49, 39, 37, 33, 26, 15, ? @@@@@ answer is 16 (49-37=12) and (37-26=11) (26-x=10)

5)35, 57, 12, 14, 2,7, 9, 42, 67, ?
Is the given series is correct?
If the series is change to 35,57,12,14,27,9,42,67,? then the answer is 13.
Break the series as 3 terms 35,57,12 and 14,27,9 and 42,67,?
now 35=5*7 i.e the next number (57) will come by putting the factors of previous number and the next number (12) will come by adding two factors.(5+7)
similarly 14 = 2*7
next number=27(Putting the factors together)
next number 9 = 2+7
next series
42 = 6*7
next number 67 (Putting the factors together)
Ans number = 6+7 = 13


6)25, 13, 39, 17, 51, 19, 57, 15, 45, ?
25-13=12
39-17=22
51-19=32
57-15=42
45-x=52 so
x= -7 ans



7)0, 1, 0, 2, 2, 2, 3, 4, 5, 6, 6,? @@@@@@@@@ 6

8)0, 1, 2, 0.5, 2, 3, 5, 1, 2, 0, 2, 1, 4, 2, 3, ? @@@@@@@@@@@may be question missing exact terms

9)2.2, 5.5, 8, 36, 40.5, 263.25, 340, 748, 1714, ?@@@@@@@@@@@ 17997 is ans..[2.2*2=4.4+(2.2/2)=5.5] [8*4=32+(8/2)=36] [1714*10+(1714/2)]

3)

( 22, 19.5, 21.45), (33, 30.5, 33.55),( 44, 41.5 , x)

first terms of brackets => 22 , 33 , 44
second terms of brackets => 19.5 , 19.5 + 11 , (19.5 + 11*2)
third terms of brackets => 21.45 , (21.45 + 12.1) , (21.45 + 2*12.1)

=> x = 21.45 + 2 * 12.1 = 45.65

question 1:
the series may be like:
-3,6,1,-2,4,-1,-1,2,-3,x,y,z

-3,-2,-1, so x=0
6,4,2, so y=0
1,-1,-3, so z=-5
