- ans is 30
34+4+21=59
43+3+20=66
12+2+16=30
- 10 years agoHelpfull: Yes(49) No(1)
- 34+4+21=59
43+3+20=66
12+2+16=30 ANS - 10 years agoHelpfull: Yes(8) No(0)
- 30
34+4+21=59
43+3+20=66
Accordingly,
12+2+16=30 (Answer) - 10 years agoHelpfull: Yes(6) No(0)
- 34+4+21=59
43+3=20=66
12+2+16=30 - 10 years agoHelpfull: Yes(5) No(0)
- 34+4+21=59(next term)
43+3+20=66("") so
ans is 12+2+16=30 - 10 years agoHelpfull: Yes(3) No(0)
- 34+4+21=59
43+3+20=66
12+2+16=30
answer will be 30
- 10 years agoHelpfull: Yes(2) No(0)
- 34+4+21=59
43+3+20=66
12+2+16=30
ans is 30 - 10 years agoHelpfull: Yes(2) No(0)
- taking pairs 34,4 21,59 43,3 20,66 12,2 16,x
diff between 34-4=30,43-3=40,12-2=10 and 59-21=38,66-20=46,x-16=?
we see in first set 40-30=10 therefore 46-38=8....therefore x is 16+8=24.
ans 24.... - 10 years agoHelpfull: Yes(1) No(4)
- 34+4+21=59
43+3+20=66
12+2+16=30 - 10 years agoHelpfull: Yes(1) No(0)
- 34+4+21=59
43+3+20=66
12+2+16=30 - 10 years agoHelpfull: Yes(1) No(0)
- divide the series into 3 parts
34+4+21=59
43+3+20=66
12+2+16=30
the ans is 30 - 10 years agoHelpfull: Yes(1) No(0)
- 30...1)divide 3 series
2)add first 3 number gives 4th one. - 10 years agoHelpfull: Yes(1) No(0)
- (34+4+21)->59
(43+3+20)->66
(12+2+16)->30 - 10 years agoHelpfull: Yes(0) No(0)
- 40 16+12+2=40
- 10 years agoHelpfull: Yes(0) No(0)
- ans. 30
34+4+21=59
43+3+20=66
12+2+16=30 - 8 years agoHelpfull: Yes(0) No(0)
- ans is 30,explanation: 34+4+21=59
43+3+20=66
12+2+16=30 - 5 years agoHelpfull: Yes(0) No(0)
- 34+4+21=59
