Help me on this please !!

Step-by-step explanation:

Hey, there !!

It's simple lets get started with simple solution,

Given the sequences are,

10,8,6,4....

Then,

common diifference= 2

now, we have formula,

Therefore, The answer is an = 2( n+4) or, 10+2(n-1)...

{ note: 2(n+4) is simplified form of 10 +2(n-1).}

Hope it helps...

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
