(1,3)(4,-3)
slope = (-3-3) / (4 - 1) = -6/3 = -2
y = mx + b
slope = -2
use either of ur points....(1.3)...x = 1 and y = 3
now sub and find b, the y int
3 = -2(1) + b
3 = -2 + b
3 + 2 = b
5 = b <===
Answer:[m, m+d, m+2d, - - - - -, n]
Step-by-step explanation:
We know the formula for arithmetic progression is a_(n) = a_(1) + (n-1)d
Where a_(n) is the nth term of the sequence
a_(1) is the first term of the sequence
n is the number of the term like if we are talking about 7th term so the n is 7.
d is the difference between two successive terms.
For this problem we know our first term that is m, our last term that is n and our difference that is d.
For second term we will use the formula
a_(2) = m + (2-1)d
a_(2) = m + (1)d
a_(2) = m + d
Similarly,
a_(3) = m + (3-1)d
a_(3) = m + (2)d
a_(3) = m + 2d
