4.) 7,19,43,91,187.......
Solution : 7*2+5=19
19*2+5=43
similarly 187*2+5=379

5) 7/6,3/2,1,5/6,13/6,2,1/2.....
Solution: (7/6,5/6,1/2) (3/2,13/6) (1,2)
actually there are three series mixed together
5/6-7/6= -1/3
1/2-5/6= -1/3
now taking
13/6-3/2 =2/3
so the next term will be 13/6+2/3= 17/6
answer is 17/6

8.) -23,-16,18,14,-52,-45,37,33,-65.................
Solution : -16-(-23)= 7
14-18= -4
-45-(-52)= 7
33-31= -4
-65+7= -58
Answer is -58

5) 7/6, 3/2, 1, 5/6, 13/6, 2, 1/2.........
(7/6, 3/2, 1),(5/6, 13/6, 2),(1/2, ?, ?(3))
we need to find out for first question mark....
7/6 - 5/6 = 2/6-------> 5/6 - 1/2 = 2/6
3/2 - 13/6 = -2/3------>13/6 - x = -2/3--------> X = 17/6
1 - 2 = -1 ------------>2 - 3 = - 1

so, correct ans is.......... 17/6

Sivagami  (9 years ago)

5) (7/6,3/2,1),(5/6,13/6,2),(1/2, x,x)

7/6- (5/6)= 1/3

5/6 -1/2 = 1/3

after that, next series -> 3/2 - 13/6 = - 2/3

13/6 - x = - 2/3 => 13/6 + 2/3 = 17/6.
ans : 17/6.
