1.5+.8=2.3
2.3+.8=3.1
3.1+.8=3.9
3.9+.8=4.7 the difference is only no.8.so we can add 8 to the previous number.
2.3+.8=3.1
3.1+.8=3.9
3.9+.8=4.7 the difference is only no.8.so we can add 8 to the previous number.

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.

This is simple, the logic is 1.5+0.8 = 2.3.
So, by the addition of 0.8, the number will increases.
So, by the addition of 0.8, the number will increases.

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.

Every no. is increasing by 0.8.
So 1.5+0.8=2.3.
2.3+0.8=3.1.
3.1+0.8=3.9.
Then 3.9+0.8=4.7.
So 1.5+0.8=2.3.
2.3+0.8=3.1.
3.1+0.8=3.9.
Then 3.9+0.8=4.7.

It's a simple A.P with common difference .8.
So just add .8 to 3.9.
You get the answer 4.7.
