2.3-1.5 = 0.8.
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.

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

The formula is +0.8 to the number in the question to get the sum :
1.5+0.8 = 2.3,
2.3+0.8 = 3.1,
3.1+0.8 = 3.9,
3.9+0.8 = 4.7.
Therefore the answer is 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.
Therefore the answer is 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
So answer is C.
3.1 - 2.3 = 0.8.
3.9 - 3.1 = 0.8.
x - 3.9 = 0.8 => x = 0.8 + 3.9 = 4.7
So answer is C.

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