one term of an arithmetic sequence is a17=82 and d=-6. write a rule for the nth term of the sequence. then find a10

Step-by-step explanation:

In an arithmetic sequence, we are given that:

The nth term of an arithmetic sequence,

When n=17, , we have:

82=a+(16)(-6)

82=a-96

a=82+96

a=178

Therefore, the 10th term of the sequence

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
