To describe a specific arith-
metic sequence, elijah wrote
the recursive formula:
[ f(0) = 30
f(n+1)=f(n)+7
write a linear equation that
models this sequence

Step-by-step explanation:

We need at least two points to write the equation of a straight line.

The recursive formula that Elijah wrote is:

When we substitute n=0, we get:

The points (0,30) and (1,37) lies on this line.

The equation of this line is of the form:

where b =30 is the y-intercept and m=7 is the slope.

We plug in these values to get:

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.

You could also use the two points to find the slope:

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
