This sequence is represented as:

a(n+1) = 5 + 11n

So for 19th term, a(19) = 5 + 11*(19-1) = 203

An = a1 + (n -1)(d)
where a1 is the first term and d is the common difference.
a19 = 5 + (19 - 1)(11)
a19 = 5 + (18)(11)
a19 = 5 + 198
a19 = 203

KengaRu [80]

Answer:

GCF is 3

Step-by-step explanation:

Given the expression -9x + 15y

First, we need to find ther individual factors

-9x = -3 *3 * x

15y = 3 * 5 * y

Since 3 is common to both factors

−9x+15y = 3(-3x+5y)

Hence the GCF is 3
