To determine the next image in the series, let's analyze the pattern in the sequence:

1. The first image has a black triangle at the bottom and one star in the top right corner.
2. The second image has a white triangle and two stars, one in the top right corner and another at the bottom left, suggesting a clockwise rotation of the stars.
3. The third image features a black triangle again and three stars, with the third star following the clockwise arrangement.
4. The fourth image continues this pattern, with four stars, and features a white triangle.

From the above analysis, it can be observed that:

• The triangle color alternates between black and white with each image.
• The number of stars increases progressively with a clockwise rotation.

Following this logical pattern, the next image should have a black triangle and five stars completing the sequence.

Examining the options, image number 1 fits this pattern perfectly, where:

• It has a black triangle.
• It has five stars arranged in a similar fashion.

Therefore, the correct answer is option 1.
