Step-by-step explanation:
The common difference d of an arithmetic sequence is
d = 
- 
= 
-
Substitute in values and solve for k, that is
5k - 1 - 2k = 6k + 2 - (5k - 1)
3k - 1 = 6k + 2 - 5k + 1
3k - 1 = k + 3 ( subtract k from both sides )
2k - 1 = 3 ( add 1 to both sides )
2k = 4 ⇒ k = 2
--------------------------------------------------------
The n th term of an arithmetic sequence is
= + (n - 1)d
= 2k = 2 × 2 = 4 and
d = 5k - 1 - 2k = 3k - 1 = (3 × 2) - 1 = 5
Hence
= 4 + (7 × 5) = 4 + 35 = 39

Step-by-step explanation:
i dont know what that +... thing is
but when youre adding the negatives youre really just adding that number so this is just
48+45+42+81+84
45+42 is 87
now we have
48 + 87 + 81 + 84
87 + 81 is 168
48 + 84 is 132
now we have
168 + 132 and that is exactly 300
again dont know what the ... is so cant help you there
Answer:
1140
Step-by-step explanation:
A decagon has 10 sides so substitute it like this:
