What will come at the place of the question mark? 3, 7, 23, 95, ?
Correct answer: C. 479
- A. 62
- B. 128
- C. 479
- D. 575
Explanation
The sequence follows a pattern where each term is generated by multiplying the previous term by an increasing integer and then adding another increasing integer. Specifically, the operations are:3 x 2 + 1 = 77 x 3 + 2 = 2323 x 4 + 3 = 9595 x 5 + 4 = 479Thus, Option C (479) correctly follows this pattern. The other options do not adhere to this rule of sequential multiplication and addition, leading to incorrect answers.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.

Suppose that 20 mL of water and 20 mL of IPA are poured into a beaker, mixed, and then allowed to settle. Based on Student 2's explanation, the resulting con- tents of the beaker would best be represented by which of the following diagrams?
During a demonstration, a teacher placed 20 mL of water, 10 mL of isopropyl alcohol (IPA), and 1 drop of blue food coloring into a test tube, capped the test tube, and inverted it 6 times. Next, she added 7 g of ammonium sulfate (AS), an ionic solid, to the test tube, capped the test tube, and vigorously shook it for 10 sec. Then, over the 15 sec period immediately following the shaking, the mix- ture in the test tube completely separated into 2 distinct liquid layers (see figure).The teacher asked each of 4 students to provide an explanation for what occurred in the test tube over the 15 sec period.Student 1Over the 15 sec, the mixture separated into 2 layers because IPA is denser than water. The water layer was on top, and the IPA layer was on the bottom. The AS dissolved in the IPA only, because AS breaks apart into neutral molecules when dissolved in IPA. Blue food colouring is polar, so it dissolves in the water only.Student 2Over the 15 sec, the mixture separated into 2 layers because water is denser than IPA. The IPA layer was on top, and the water layer was on the bottom. The AS dis- solved in the water only, because AS breaks apart into neutral molecules when dissolved in water. Blue food colouring is polar, so it dissolves in the IPA only.Based on the figure, 5 see after the shaking, would the contents of the test tube have been better classified as a heterogeneous mixture or a homogeneous mixture?
