Write a recursive formula for each explicit formula
and find the first term of the sequence.

38. an = 108 -n

40.) a = 35 + 52n

38.

40.

Step-by-step explanation:

38. Given explicit formula:

When then

When then

When then

When then

and so on

You can see that each next number is 1 less than previous number, so the recursive formula is

40. Given explicit formula:

When then

When then

When then

When then

and so on

You can see that each next number is 52 more than previous number, so the recursive formula is

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
