Find the 8, 19, 21, 25, 20, ?..

Answer / n. vijaya lakshmi

Answer - 17

Solution -

8 + 11 = 19
19 + 2 = 21
21 + 4 = 25
25 + (-5) = 20
20 +/- ? = ?

Now, the real question is 11, 2, 4, -5, ?

11 - 7 = 4
2 - 7 = -5
That's how we got, 11,2,4 and -5.

Now, 4 - 7 = (-3)
subtracting -3 from 20, we get 17.

Answer / $hawn

Ans = 17.


8 19 21 25 20 x1

|_______| |_____| |_____| |_____| |______|
| | | | |

11 2 4 5 x2

|_______| |_____| |_____| |______|
| | | |

-9 2 -9 x3


Here x3 should be 2 bcoz the sequence is -9, 2, -9, 2,...

thus x2 = -5 + 2 = -3

and hence x1 = 20 + (-3) = 17

thus the answer 17.

In the middle of the confounded desert, there is the lost city of "Ash". To reach it, I will have to travel overland by foot from the coast. On a trek like this, each person can only carry enough rations for five days and the farthest we can travel in one day is 30 miles. Also, the city is 120 miles from the starting point. What I am trying to figure out is the fewest number of persons, including myself, that I will need in our Group so that I can reach the city, stay overnight, and then return to the coast without running out of supplies. How many persons (including myself) will I need to accomplish this mission?
