a1=5,d=-4/3

Find a formula for the arithmetic sequence.

a1=5,d=-4/3

5 = 5+0(–4/3),

5+(-4/3) = 5+1(–4/3),

5+(-4/3)+(-4/3) = 5+2(–4/3),

5+2(–4/3)+(–4/3) = 5+3(–4/3),

…

5+(n–1)(–4/3)

a1=5,d=-4/3

5 = 5+0(–4/3),

5+(-4/3) = 5+1(–4/3),

5+(-4/3)+(-4/3) = 5+2(–4/3),

5+2(–4/3)+(–4/3) = 5+3(–4/3),

…

5+(n–1)(–4/3)
