Put the equation in slope intercept form first. it’ll look somewhat like
y=mx+b (m is your slope and b is your y-intercept). you find your slope by drawing slope triangles. to draw a slope triangle, find two points and draw a triangle to connect them together. then you see how many it goes up/down and how many it goes to the side, left/right. the y-intercept is where the point crosses the y axis when x is 0.

To describe a specific arithmetic sequence, Elijah wrote the recursive formula:
11111nata11111 [884]

Answer:

t_{n}  = 30 + 7n, where, n = 0, 1, 2, 3, 4, .........

Step-by-step explanation:

Given the arithmetic sequence in recursive formula.

f(0) = 30 and f(n + 1) = f(n) + 7 ......... (1)

Therefore, putting n = 0 in equation (1) we get f(1) = f(0) + 7 = 30 + 7 = 37 {Since, f(0) is given to be 30}

Again, putting n = 1 in equation (1) we get f(2) = f(1) + 7 = 37 + 7 = 44

And, putting n = 2 in equation (1) we get f(3) = f(2) + 7 = 44 + 7 = 51

and so on.

Therefore, the arithmetic sequence is 30, 37, 44, 51, .......

Therefore, the linear equation of this sequence is given by t_{n}  = 30 + 7n, where, n = 0, 1, 2, 3, 4, .........
