Find the step between consecutive terms by checking the known gaps.<br><br>
&bull; From 2.1 to 2.7, there are 2 steps: 2.7 − 2.1 = 0.6, so each step = 0.6 ÷ 2 = 0.3.<br>
&bull; From 3.0 to 3.6, there are 2 steps: 3.6 − 3.0 = 0.6, also 0.3 per step (consistent).<br>
&bull; First blank: 2.1 + 0.3 = 2.4<br>
&bull; Second blank: 3.0 + 0.3 = 3.3<br>
&bull; Sequence: 2.1, 2.4, 2.7, 3.0, 3.3, 3.6<br><br>
Final Answer: 2.4, 3.3
