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

Answer:
![4 \sqrt[3]{6x}^{2}](https://tex.z-dn.net/?f=4%20%5Csqrt%5B3%5D%7B6x%7D%5E%7B2%7D)
Step-by-step explanation:
a like radical just means one that's similar to the original. going through your options, you should look for one with the exact same contents in the brackets as the one asked in the question. in this case, we see it's the third one because the contents inside are the same. the outside value (or known as the stretch/compression value) doesn't change the fact that it is still like to the original.
3/2 is the correct answer for your problem
