what comes next?

7, -35, -34, -3, 15, 16, 4

a) -20
b) -15
c) 5
d) 21
e) 33

• 7*-5=-35, then -35+1=-34
  -3*-5=15,then 15+1=16
  so 4*-5=-20

• Multiply -5 in each case
  7*-5 =-35 then -35+1 =-34
  -3*-5 15 then 15+1 =16
  so,,,,, 4*-5 =-20
• 8 years agoHelpfull: Yes(2) No(1)
• 7*-5=-35
  -35+1=-34 (i.e., 7,-35,-34)
  -3*(-5)=15
  15+1=16 (i.e., -3,15,16)
  (4,x,x)?
  4*(-5)=-20
  -20+1=-19 (i.e., 4,-20,-19)
  therefore the next term is -20.

• first we need to divide the series in set of 3,series logic is as (*-5) for 2nd number and (+1) for 3rd number
  and finally the ANS:-20
• 8 years agoHelpfull: Yes(1) No(0)
• 7x(-5)=-35+1=34
  -3 x (-5)=15+1=16
  4 x (-5)=-20+1=-19
  so ans is -20
  and series r 7, -35, -34, -3, 15, 16, 4, -20, -19

• 
  7*-5=-35;-35+1=-34
  -3*-5=15;15+1=16
  4*-5=-20;-20+1=-19
  nd so on
  so option will be =(a)

• 7*-5=-35,-35+1=34,-3*-5=15,15+1=16,4*-5+-20
  ans:-20

• 7*-5=-35, then -35+1=-34
  -3*-5=15,then 15+1=16
  so 4*-5=-20

• Ans. a) -20
  7,7*-5,-35+1,-3,-3*-5,15+1,4,4*-5=-20
• 8 years agoHelpfull: Yes(0) No(0)
• a is the solution
  
• 8 years agoHelpfull: Yes(0) No(0)
• solution -> 'a'
  -> 7* -5= -35,
  -35+1=-34
  -> -3* -5=15,
  15+1=16
  -> 4* -5= -20.

• 7*-5=-35,-35+1=-34,-3*-5=15,15+1=16,4*-5=20
• 8 years agoHelpfull: Yes(0) No(0)
• 7*(-5)=-35+1=>-34 same logic apply
• 8 years agoHelpfull: Yes(0) No(0)
• -20 is the answer
• 8 years agoHelpfull: Yes(0) No(0)
• ans is d
  because 7*-5=-35 then +1
  in next series -3*-5=15 then +1=16
  
• 8 years agoHelpfull: Yes(0) No(0)
• a)-20
  7*(-5)= -35;
  -35+1=-34;
  now -
  -3*(-5)=15;
  15+1=16;
  now 4*(-5)=-20ANS

• 7*-5=-35 then add 1=-34
  -3*-5=15 then add 1=16....
  so on
  
• 8 years agoHelpfull: Yes(0) No(0)
• 7*-5=-35
  -35+1=34
  -3*-5=15
  15+1=16
  then4*-5=20

• Above question follow the logic:
  First term is multiplied by -5 and in third term 1 is added and hence the 4x-5 will result: -20
