f(1)=−8 f(n)=f(n−1)−3 Find an explicit formula for f(n)

  f(n) = -8 -3(n -1)

Step-by-step explanation:

The given recursive formula tells you that the difference between two sequential terms is -3, and that the first term is -8. This is a formula for an arithmetic sequence, so we can use the explicit formula ...

  f(n) = a1 +d(n -1)

for a1 = -8 and d = -3.

  f(n) = -8 -3(n -1)

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google
