Answer:
Yes, 12:18 is simplified to 2:3
Step-by-step explanation:
Answer:
The area of the rectangle is 12
6x2=12
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
Answer:
Step-by-step explanation:
4^(4-7+1) = 4^-2
