Assessment #17 review

Topic #20 Arithmetic Sequences

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

f(1) = 1st term

d = common difference (what you are adding or subtracting to get to the next term

Multiple Choice

f(n) = 2 + 4(n-1)

Find the 10th term using the sequence

• 36

• 38

• 34

• 40

Recursive Formula

a(1) = 1st term

a(n) = a(n-1) + d

d= common difference
