Pick the figure from the options that best continues the given figure series.

Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
From each figure to the next, one small circle is added each time (1, 2, 3, 4 small circles). So the next figure has 5 small circles.

Why the other options are incorrect
Option (2) — Incorrect. There are 3 small circles: a small circle is taken away instead of added.
Option (3) — Incorrect. The number of small circles has not changed: there are still 4, as in the last figure.
Option (4) — Incorrect. There are 6 small circles: two small circles are added instead of one.
