Answer:
the first term is a1
the distance between the numbers is d
we have:
a5 = a1 + 4d = 23
a12 = a1 + 11d = 72
so we have the equation:
a1 + 4d = 23
a1 + 11d = 72
=> a1 = -5
d = 7
=> an = -5 + 7(n - 1) = 7n - 12
with an = 7n - 12
=> a2 = 2
a3 = 9
so the first three terms is -5; 2; 9
Answer:
f(x) is shifted 1 unit left
Step-by-step explanation:
The transformation accomplished by f(x-h) is to shift the graph of the function f(x) to the right by "h" units. Here, the value of h is -1, so the graph is shifted left by 1 unit.
