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

At 7:00 a.m., the temperature was 8°C. What was the temperature at midnight if the temperature was 10° lower? Incorrect answer
astra-53 [7]

Answer:

b)−2° C

Step-by-step explanation:

hello! To solve this problem you should remember how are the operations with negative numbers, for this the only thing we must do is make a subtraction between the initial temperature (8° C) and the negative change of temperature (10° C)

Ti= initial temperature =8° C

ΔT= temperature change  =10° C

new temperature=Ti-ΔT

new temperature=8° C-10° C=-2° C

in conclusion the answer is -2° C

Explain why 235 is not divisible by 7
otez555 [7]
Because 35 is divisible by 7, but 23-21=2, so it becomes 25, which 7 is not a factor of. therefore, it is not divisible by 7.
