Notice the difference between each term:
1, 3, 9, 27
To get to the next number you add the next power of 3 (81, 243, etc.)
4 + 1 = 5
5 + 3 = 8
8 + 9 = 17
17 + 27 = 44
44 + 81 = 125
125 + 243 = 368
368 + 729 = 1097
etc.
4, 5, 8, 44, 125, 368, 1097, etc.
So the next term is: 125
4 5 8 17 44
4 + 3^0 = 4 + 1 = 5
5 + 3^1 = 5 + 3 = 8
8 + 3^2 = 8 + 9 = 17
17 + 3^3 = 17 + 27 = 44
44 + 3^4 = 44 + 81 = 125
5-4 =1
8-5=3
17-8=9
44-17= 27
then 81
which means the missing figure is 125
125
4 +1 = 5; 5+(1×3)=8; 8+(3×3)=17; 17+(3x3x3=44;
so 44+(3x3x3x3)=125
Answer 6
the next in the series is 125. Each number you add the next perfect cube… as in 1 3 9 27 81 etc.
Answer 7
125
125
Source(s): it goes up by x3 each time…4-5=1, 5-8=3, 8-17=9, 17-44=27,….
81
