Step-by-step explanation:
Not all functions will have intercepts, but when you are working with the graph of a linear function, it will have both an x-intercept and a y-intercept. An x-intercept is where the graph crosses the x-axis and a y-intercept is where it crosses the y-axis. Let's think about a line that crosses the x-axis.
The appropriate formula here is l = a + (n-1)d, where l represents the last term.
Here the first term is -5 and the common difference is +4. Thus,
l = -5 + (n-1)(4) (answer)
Check: we are given the arith sequence -5, -1, 3, 7. Does our formula correctly predict the 1st term? l = -5 + (1-1)(4) = > -5. Yes.
Does it correctly predict the 3rd term? l = -5 +(3-1)(4) => -5+2(4) = 3. Yes
