Step-by-step explanation:
<span>I am detailing it to show you how to calculate an explicite equation
Arithmetic Progression First term 7 , second 3 hence d=3-7 = - 4</span>
n=Term rank ==>║ 1 2 3 4 5 6 7......n
Value ====>║ 7 3 -1 -5 -9 -13 -17.......
a(n) (sub Notation║ a₁ a₂ a₃ a₄ a₅ a₆ a₇.....a(n)
Term 1 = a₁ = 7........................7-4(0)
Term 2 = a₂ = 3........................7-4(1)
Term 3 = a₃ = -1.......................7-4(2)
Term 4 = a₄ = -5.......................7-4(3)
Term 5 = a₅ = -9.......................7-4(4)
Term n = a(n) ============7-4(n-1)
So A. an = 7 − 4(n − 1); all integers where n ≥ 1
