- Answer B
3×1+1=4
4×2+2=10
AND so on - 8 years agoHelpfull: Yes(8) No(10)
- 4/3 remainder 1
10/4 remainder 2
33/10 remainder 3 (32 is not the correct one)
136/33 remainder 4
and so on.. - 8 years agoHelpfull: Yes(8) No(3)
- 3 * 1 + 1 = 4
4 * 2 + 2 = 10
10 * 3 + 3 = 33(not 32)
33 * 4 + 4 = 136
136 * 5 + 5 = 685
685 * 6 + 6 = 4116
So Answer is B - 8 years agoHelpfull: Yes(3) No(0)
- answer is B(32)
Explanation:
3 * 1 = 3 +1=>4
4 * 2 = 8 +2=>10
10 * 3 = 30+3 =>33
33 * 4 =132 + 4=>136
136 * 5=680 +5=>685
685 * 6=4110+6=>4116
so,it is clear that odd one is 32. - 7 years agoHelpfull: Yes(3) No(0)
- 3*1+1=4
4*2+2=10
10*3+3=33
So 32 - 8 years agoHelpfull: Yes(2) No(2)
