Answer:
Yes the sequence is arithmetic
The common difference is 6
Step-by-step explanation:
Determine whether the following sequences are arithmetic. If so, identify the common difference.
9, 15, 21, 27, ...
The sequence given in the above question is arithmetic because it follows the formula
Un = a + (n -1)d
Where
a= First term
n = Number of terms
d = Common difference
The common difference is calculated as the
Second term - First term
15 - 9
= 6
or the Third term - Second term
21 - 15
= 6
or the Fourth term - Third term
= 27 - 21
= 6
Therefore, the Common difference = 6

Module 4, students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, lines, and linear equations in this module. Students learn to apply the skills they acquired in Grades 6 and 7, with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables.
The student materials consist of the student pages for each lesson in Module 4.
The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.
Answer:
Doubling the actual answer and increasing it by 2.
Step-by-step explanation:
The calculator is returning 26, instead of 12. Note that 26 is 2 more than twice of 12.
i.e.
26 = 2(12) + 2
Calculator is returning 32 instead of 15. Here again we can note the same logic. 32 is 2 more than twice of 15.
i.e.
32 = 2(15) + 2
Calculator returns 202 instead of 100. Here again the same logic holds true.
i.e.
202 = 2(100) + 2
So, what the calculator is doing is:
Doubling the actual result and increasing it by 2.
