Arithmetic Sequences Practice

f(0) = 20, f(1)=23. f(n)=____________

*Note: Do not type "f(n) =" and do not use spaces in your answer when typing.

f(0) = 32, f(1)=28. f(n)=____________

f(1) = 7, f(2)=10. f(n)=____________

f(1) = 25, f(2)=31. f(n)=____________

f(3) = 9, f(4)=11. f(n)=____________

The first term of an arithmetic sequence is 18. The common difference is -4. What is the rule? f(n) = __________

The second term of a sequence is 55. The common difference is 8. What is the tenth term?

The first term of a sequence is -31. The common difference is 4. What is the 50th term?

The recursive rule for a sequence looks like this:

f(1)=-8

f(n)=f(n-1)+5

What is the explicit rule? f(n)=__________

The recursive rule for a sequence looks like this:

f(1)=22

f(n)=f(n-1)-4

What is the explicit rule? f(n)=__________
