- 1. 1516
4+7=11,11*6=66,66+8=74,74*5=370,370+9=379,379*4=1516
2.
3. 140
5*3+1=16,22*3+2=68,28*3+3=87,34*3+4=140 - 11 years agoHelpfull: Yes(13) No(13)
- 3. 5*3=15 15+1=16
22*3=66 66+2=68
28*3=84 84+3=87
34*3=102 102+4=106 ans - 11 years agoHelpfull: Yes(10) No(0)
- 4+7=11, 11*6=66, 66+8=74, 74*5=370, 370+9=379, 379*4=1516

- 1.let me make it more simple
(4,11)(66,74)(370,379)(x,y)
11-4=7
74-66=8
379-370=9
x-y=10
(4,11)(66,74)(370,379)(x,y)
for shifting from one bracket to another see 11*6=66
74*5=370
379*4=1516
howz it :-)

- 2) 2/3+0=2/3
2/3+1=5/3
5/3+2/3+3=16/3
16/3+5/3+2/3+0=23/3
23/3+1=26/3
anz =26/3 - 11 years agoHelpfull: Yes(3) No(13)
- 2) (2/3 +1)*1= 5/3
(5/3 +1)*2= 16/3 =32/6
(16/3 +1)*3= 19
so ans = 19 - 10 years agoHelpfull: Yes(2) No(5)
- 2)2/3+1=5/3
32/6+2=42/6
2/3+3=11/9 - 10 years agoHelpfull: Yes(1) No(3)
- 2. rewriting the seq as 2/3, 5/3, 16/3, 72/3....
leaving the first two nos, we have--
2*5+6= 16
16*5-8=72
72*5+10=370
ans is 370/3. - 10 years agoHelpfull: Yes(1) No(0)
- 1) 4+8=11
11*6=66
66+7=74
74*5=370
370+9=379
379*4=1516
