We can make chain also. It is direct method.
3.1-1.5=1.6
3.1+1.6=4.7
3.1-1.5=1.6
3.1+1.6=4.7

1.5 + 0.8 = 2.3,
2.3 + 0.8 = 3.1,
3.1 + 0.8 = 3.9,
3.9 + 0.8 = 4.7.
2.3 + 0.8 = 3.1,
3.1 + 0.8 = 3.9,
3.9 + 0.8 = 4.7.

2.3-1.5=0.8
3.1-2.3=0.8
3.9-3.1=0.8
x-3.9=0.8
x=0.8+3.9=4.7=ans.
3.1-2.3=0.8
3.9-3.1=0.8
x-3.9=0.8
x=0.8+3.9=4.7=ans.

15, 23, 31, 39, ?
31-15 = 16.
39-23 = 16.
So 31+16 = 47.
31-15 = 16.
39-23 = 16.
So 31+16 = 47.
