Answer:

From the choices given, the most reasonable estimate is 25.

Step-by-step explanation:

5 sections on the spinner means there is a 1/5 chance of landing on any of the sections each spin.

This means landing on a section labeled 5 should happen 1/5(150) = 30 times.  The closest option to this is 25.

What is the sum of the arithmetic sequence 151, 137, 123,..if there are 26 terms?
ElenaW [278]
First term: a1 = 151
common difference: d = -14 (we decrease by 14 each time, eg, 151-14 = 137)

nth term of this arithmetic sequence is...
an = a1+d(n-1)
an = 151+(-14)(n-1)
an = 151-14n+14
an = -14n+165

This will be used in the formula below

Sn = n*(a1+an)/2
<span>Sn = n*(151+(-14n+165))/2
</span><span>S26 = 26*(151+(-14*26+165))/2 ... replace every n with 26
</span>S26 = -624

The final answer here is choice C) -624
