- consider 7=1st term, 8=3rd term, (7+1=8) increased by +1
consider 5=4th term, 7=6th term, (5+2=7) increased by +2
consider 7,6 decreased by -1 ,
consider 5,3 decreased by -2 ,
then next term should be 7-3 = 4 (decreased by -3 ) ans 4 - 11 years agoHelpfull: Yes(17) No(8)
- 7+6-8=5
5+3-7=1
so series will be
7,6,8,5,3,7,1 - 12 years agoHelpfull: Yes(11) No(30)
- 6+8=14/2=7
3+7=10/2=5
0+6=6/2=3
so. 3 is the answer Enjoy it....... - 11 years agoHelpfull: Yes(3) No(9)
- 7-1=6,7+1=8
5-2=3,5+2=7
3-3=0,3+3=6
So pattern is first number, 1st answer, 2nd answer
First number decreases by 2 each time, second number is 1st-n, and third number is 1st+n
So answer should be 3 - 8 years agoHelpfull: Yes(2) No(2)

3-3=0
3+3=6
so ANS: 3 - 8 years agoHelpfull: Yes(1) No(2)
- 6-7=-1, 8-6=2, 5-8=-3, 3-5=-2, 7-3=4

- "Chain Group by 3: average(x,y),x,y; a,b,c and a=(average(x,y)+x)/3

5,3,7
?" - 8 years agoHelpfull: Yes(0) No(1)
- 7-1=6 7+1=8
5-2=3,5+2=7
3-3=0,3+3=6 - 8 years agoHelpfull: Yes(0) No(1)
- consider each 3 elements in a group 7,6,8
take middle term 6
first 6+1=7
7+1=8
next 6-3=3
take another three elements
5,3,7
middle term is 3
next 3+2=5
5+2=7
so next 3 elements will be
3-3=0
middle term will be 0 and now increment will be 3
so 0+3=3
3+3=6
so three elements will be 3,0,6
so ans will be 3. - 8 years agoHelpfull: Yes(0) No(0)
- 7-1=6 (7,6,8)
7+1=8
5-2=3(5,3,7)
5+2=7
3-3=0(3,0,6)
3+3=6

- 7,6,8,5,3,7,?
divide in 3 part
first part is 7,5,3 sub. by -2
second part is 6,3,... so on sub by -3
third part is 8,7,... so on sub. by -1
Ans is = 3 - 7 years agoHelpfull: Yes(0) No(0)
- 7-1 =6 5-2=3 3-3=0;
7+1=8; 5+2=7 - 7 years agoHelpfull: Yes(0) No(0)
