Answer:
second difference
Step-by-step explanation:
The differences of the y-values will differ by a common amount.
<u>Example</u>:
y = x^2 for x = 2, 4, 6, 8
y-values are 4, 16, 36, 64
differences of these are 12, 20, 28
differences of these differences are 8 and 8, a common value.
The 9 is in the tenths place so it should be 9x1/10. Meaning it would be 100+3x1+9x1/10+3x1,000
Answer:
<em>The integers are 39 and 40.</em>
Step-by-step explanation:
Let the smaller integer be x.
The next greater integer is x + 1.
Their sum is x + x + 1.
Their sum is 79, so
x + x + 1 = 79
Solve for x.
2x + 1 = 79
2x = 78
x = 39
x + 1 = 40
Since a(n)=-3(a(n-1)) the common ratio is -3, and a(1)=-3 so
a(n)=-3(-3^(n-1)) so the first four terms are:
-3, 9, -27, 81
