- (124 , 62) ,( 60 , 30 ), (28 , 14 )
124/2 = 62 - 2 = 60
60/2 = 30 - 2 = 28
28/2 = 14 - 2 = 12
12/2 = 6 - 2 = 4
Answer is 12, 6 and 4 - 11 years agoHelpfull: Yes(4) No(0)

Division of two number and then sustract 2 from second number - 11 years agoHelpfull: Yes(2) No(0)
- 124 = 62 * 2
60 = 30 * 2
28 = 14 * 2
12 = 6 * 2 - 11 years agoHelpfull: Yes(1) No(1)
- 60*2+4=124,28*2+4=60,12*2+4=28,4*2+4=12.
30*2+2=62,14*2+2=30,6*2+2=14
Ans= 12,6,4 - 11 years agoHelpfull: Yes(1) No(0)
- the pattern goes like this:
124-62=62 (after diff of 2) 60;
60-30=30 (after diff of 2) 28;
28-14=14 (after diff of 2) 12;
12-6=6 (after diff of 2) 4;
4-2=2

- n+1th term = (nth term /2) if n+1 is even else (nth term -2) .............so
124,62,60,30,28,14,12,6,4..... - 11 years agoHelpfull: Yes(0) No(1)
- 124=62*2
62-2=60
60=30*2
30-2=28
28=14*2
14-2=12
12=6*2
6-2=4
ans is 12,6,4 - 11 years agoHelpfull: Yes(0) No(2)
- 62*2=124
60+2=62
30*2=60
28+2=30
14*2=28
12+2=14
6*2=12
4+2=6
2*2=4
So...Ans is=12,6,4 - 11 years agoHelpfull: Yes(0) No(3)
- 12 and 6
62+62=124
diff between 62 to 60=2
30+30=60
diff between 30 to 28=2
14+14=28
diff between 14 to 12=2
6+6=12
- 11 years agoHelpfull: Yes(0) No(1)
- ans is 12
60+60=120+4=124
28+28=56+4=60
2x+4=28
=12 - 11 years agoHelpfull: Yes(0) No(0)
- series follows /2,-2
next will be 12,6,4,2,0 - 9 years agoHelpfull: Yes(0) No(0)
