(a) - Common ratio, r ==3/15 == 1 / 5
(b) The formula for the nth term of the sequence is: a(n) =3 * 5^(2 - n)
(c) Find the 10th term of the sequence. Use the above formula in (b)
a(10) =3 * 5^(2 - 10) =3 x 5^(-8) =3 * 1/390,625 =3 /390,625 - this is the 10th term
please help asap please and thank you.
