Given:
and 
where 
.
To find:
The explicit formula for the given recursive formula.
Solution:
We know that recursive formula of an AP is:
Where, d is the common difference.
We have,
Here, d=9.
The first term of the AP is .
The explicit formula for an AP is:
Substituting and 
, we get
Therefore, the required explicit formula for the given sequence is .
Answer:
2 relative maxima and minima
(2, 6.2) = maxima
(0, -4) = minima

Answer:
It's y=4x+3
Step-by-step explanation:
if you find the slope m=(y2-y1)/(x2-x1). Then you know the y-intercept is 3 because it gives you the point (0,3).
Numbers are 416, 417 and 418
<u>Step-by-step explanation:</u>
Step 1:
Let the numbers be x, x + 1 and x + 2. Given that their sum is 1251.
⇒ x + x + 1 + x + 2 = 1251
⇒ 3x + 3 = 1251
⇒ 3x = 1248
⇒ x = 416
Step 2:
Find the other numbers.
⇒ x + 1 = 417 and x + 2 = 418
Yes "3x8 = 4x6" does illustrate the commutative property of multiplication.
