Answer:
an = -9 + 7( n - 1)
Step-by-step explanation:
an = first term + difference (n-1)
First term = 9
Difference = -2 - -9 = -2 + 9 = 7
an = -9 + 7( n - 1)
You can check this by substituting the values in.
a1 = -9 + 7(0) = -9
a2 = -9 + 7(2) = -9 + 7 = -2
a3 = -9 + 7(3) = -9 + 14 = 5
38773 - 14056 = 24717
24717 + 14056 = 38773
