Step-by-step explanation:
Answer:
A:∑j=15(2j−5)
Step-by-step explanation:
a = -3
d = -1 - (-3) = -1 + 3 = 2
j-th term: a + (j-1)d
-3 + (j - 1)(2)
-3 + 2j - 2
2j - 5
Answer:
55
Step-by-step explanation:
The n-th term of an arithmetic sequence is given by the formula ...
an = a1 + d(n -1)
where a1 is the first term (5.5) and d is the common difference (0.5).
So, the n-th term is ...
an = 5.5 +0.5(n -1) = 5.0 +0.5n
For n = 100, the term is ...
a100 = 5.0 +0.5(100) = 55
The 100th term of the sequence is 55.
