Question

angela is designing a 4 - story building, and as she is creating the blueprint, she realized that there wasn’t a cons change with the number of steps between the floors like she envisioned. look at angelas work below and state which transition to the next floor needs to be corrected. | floor | steps | | --- | --- | | 1st to 2nd floor | 2 | | 2nd to 3rd floor | 4 | | 3rd to 4th floor | 7 |

Explanation:

Step1: Analyze the pattern

Check the differences between consecutive step counts. From 1st to 2nd: 2 steps. From 2nd to 3rd: 4 steps (difference of \(4 - 2 = 2\) if we assume a constant increase, but wait, actually we need to check the intended constant change. Wait, maybe the intended pattern is a constant difference or a constant ratio? Wait, the problem says "cons change" (probably "constant change"). Let's check the differences: 2 to 4 is +2, 4 to 7 is +3. So the change from 3rd to 4th is not consistent with the previous +2. Wait, or maybe the intended pattern is arithmetic sequence with common difference. Wait, 2, 4, next should be 6 (since 2 + 2 = 4, 4 + 2 = 6), but it's 7. So the transition from 3rd to 4th floor (steps from 4 to 7) is incorrect. Alternatively, maybe the pattern is 2, 4, 6 (adding 2 each time). So the 3rd to 4th floor transition (steps 7) is wrong.

Step2: Confirm the inconsistency

The first transition (1st - 2nd) is 2 steps. Second (2nd - 3rd) is 4 steps (increase by 2). Third (3rd - 4th) is 7 steps (increase by 3), which breaks the constant increase of 2. So the 3rd to 4th floor transition needs correction.

Answer:

The transition from 3rd to 4th floor (3rd to 4th floor) needs to be corrected.
