Given:
The arithmetic sequence is:
10, 12, 14, 16, ...
To find:
The function that generates the given sequence if n is an integer.
Solution:
We have,
10, 12, 14, 16, ...
Here, the first term is 10 and the common difference is:



The nth term of an arithmetic sequence is:

Where, a is the first term, d is the common difference and
.
Putting
in the above formula, we get



Therefore, the function
generates the sequence.
P = 2(L + W)
P = 25
L = W + 3
now we sub and solve
25 = 2(W + 3 + W)
25 = 2(2W + 3)
25 = 4W + 6
25 - 6 = 4W
19 = 4W
19/4 = W
4.75 = W <== width = 4.75 cm (or 4 3/4 cm)
L = W + 3
L = 4.75 + 3
L = 7.75 <== length = 7.75 cm (or 7 3/4 cm)
What 2 numbers multily to get -16 and add to get -6?
