For the sequence, write an explicit formula. a₁ = 24, a₂ = 18, a₃ = 12, a₄  = 6, a₅ = 0, …

• a_n = 24 - 6(n - 1)

• a_n = -6 + 24(n - 1)

• g_n = 24 · (-2)^n-1

• g_n = -2 · 24^n-1

Write the explicit formula for arithmetic sequences.

• f(n) = f(1) + nd

• f(n) = f(1) + d

• f(n) = f(1) - (n-1)d

• f(n) = f(1)+ d(n-1)

Find an explicit rule for the nth term of the sequence.

• a_n= 15+(n-1)4

• a_n= -15+(n-1)4

• a_n= -15+(n-1)3

• a_n= 4n -19
