- 10^2-20=80
20^2-30=370
30^2-40=960
40^2-50=1550
50^2-60=2440
60^2-70=3530 - 6 years agoHelpfull: Yes(11) No(5)
- opt D
because 370-90=290
2440-1550=890
3530-2440=1090
370+490=860
so option D - 7 years agoHelpfull: Yes(7) No(4)
- 80+290=370
370+490=860
860+690=1550
1550+890=2440
2440+1090=3530
so the answer is option c)860.. - 7 years agoHelpfull: Yes(3) No(0)
- The answer will be 860
because there is a gap of 290 then +200 then +200 ....and so on
the series goes like this ..
the gap between 80 ans 370 is 290
the gap between 370 and 860 is 490
the gap between 860 and 1550 is 690
the gap between 1550 and 2440 is 890
the gap between 2440 and 3530 is 1090 - 6 years agoHelpfull: Yes(1) No(1)
- it's d. 860.. Because 80+290=370
370+290+200=860
860+290+200+200=1550
1550+290+200+200+200=2440
2440+290+200+200+200+200=3530 - 6 years agoHelpfull: Yes(1) No(0)
- Simple logic!!
80(nearest 100)= 100-80=20
next 370 (nearest 400)=400-370=30
next difference should be 40!!
Therefore see the option d. 860(nearest 900|)=900-860=40 - 5 years agoHelpfull: Yes(1) No(0)
- D) Answer
80, 370 (860) , 1550 , 2440, 3530

- We have to come from right to left:
3530-2440=1090
2440-1550=890
370-80=290
so, either 370 + 490 = 860 or 1550-690=860
Therefore, the answer is 860. - 2 Months agoHelpfull: Yes(0) No(0)
