Answer:
60 :)
Step-by-step explanation:
The middle two numbers are 59 and 61 so you add them together and divide by 2.
1st day he ran30. 2nd day he ran 35 3rd day he ran 35 and fourth day he ran 45 so 30+35+35+45 =145 minutes all together he ran
Answer:
an = -39 -100(n -1)
Step-by-step explanation:
The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...
-39, -139, -239, -339
This has a first term a1 = -39, and a common difference d = -100.
The model for the explicit formula is ...
an = a1 +d(n -1)
Filling in the given values, the formula you seek is ...
an = -39 -100(n -1)
_____
* That polynomial is ...
an = 50n^3 +350n^2 -800n +461
This gives a sequence that starts ...
-39, -139, -139, -339, -1039, -2539, -5139, -9139, ...
