Divide x by x drag the 2 over get the auadteic formula cross it over by 5 and add 6 to your answer
We are given
first term is 1
so, 
each succeeding term is found by adding 3 to the one before it
so, common difference is

Since, this is arithematic sequence
so, we can use nth terms formula

now, we can plug values
and we get

Answer:
Step-by-step explanation:
Let's say the number "n" were the largest multiple of 9. But then:
Consider n + 9. n is itself a multiple of 9, so n = 9k, so n + 9 = 9(k + 1), so n + 9 is also a multiple of 9, and n + 9 is larger than n.
So there can't be a largest multiple of 9 (or any number).
