• 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

• 7+6-8=5
  5+3-7=1
  so series will be
  7,6,8,5,3,7,1

• 6+8=14/2=7
  3+7=10/2=5
  0+6=6/2=3
  
  so. 3 is the answer Enjoy it.......

• 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

• 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.

  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
