term in the sequence

The second term in the sequence is -9

Step-by-step explanation:

Given the nth term of a sequence to be a(n) = a(n-1)+4 where n is the number of terms of the sequence

If a(1) = -13... (1)

The second term of the sequence is generated for n= 2:

a(2) = a(2-1)+4

a(2) = a(1)+4... (2)

Substituting equation 1 into 2

a(2) = -13+4

a(2) = -9

The second term in the sequence is -8

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

125 yards

step-by-step explanation:

i take 75 plus 50.
