Question

IQ test -- What is the next number in sequence 7, 2 , 0, 7, 8 , 4 , 3, ?

Answer 1

I solved it this way. 

Assume that sequence is 7,2,0,7,8,4,3, x. 

Difference between 1st and 5th term..and then 2nd and 6th..3rd and 7th, and then 4th and 8th. 

So subtracting 7 from 8 = -1
2-4 = -2
0-3= -3, and 
7-x=-4

Thus, -x = -4+-7=-11. Thus x=11. 

Your answer is 11.
