What are the explicit equation and domain for an arithmetic sequence with a first term of 7 and a second term of 3?
tino4ka555 [31]
<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
