please help and please use the wording in the given statements thank you!

By dragging statements from the left column to the right column below, give a proof by induction of the following statement:
an = 10" - 1 is a solution to the recurrence relation an = 10an-1 + 9 with a = 0.
The correct proof will use 8 of the statements below.
Statements to choose from:
10ao + 9.
Note that a₁
Then 10k+1 1 = 10(10k − 1) + 9, which is
true.
=
Therefore, by the Principle of Mathematical
Induction, P(n) is true for all n ≥ 1.
ak+1
By the recurrence relation, we have
ak+1 10ak + 9 = 10(10k − 1) +9
=
Thus P(k+ 1) is true.
Now assume that P(k + 1) is true.
This simplifies to
= 10k+1 − 10 + 9 = 10k+1

Let P(n) be the statement, "an = 10" 1 is a
solution to the recurrence relation
10an-1 + 9 with a = 0."
Now assume that P(n) is true for all n ≥ 0.
10⁰ 11-1 = 0, as

Now assume that P(k) is true for an arbitrary
integer k > 1.

10ak + 9, so P(k + 1) is true.
Thus P(k) is true for all k.
