Answer:
F(1) represents the first term of the sequence.
Step-by-step explanation:
Let us suppose the sequence function
We can find the first term of the sequence by substituting n=1 in the function sequence
We can find the 2nd term of the sequence by substituting n=2 in the function sequence
We can find the 3rd term of the sequence by substituting n=3 in the function sequence
So the first three terms of the sequence is:
13, 10, 7...
As the common difference is the same.
i.e. d = 10-13 = -3, d = 7-10 = -3
Hence, it is an Arithmetic sequence.
As the first term is 13, which can be obtained by putting n=1 in the function sequence.
Therefore, from the above discussion, we can conclude that F(1) represents the first term of the sequence.
Answer:
The other complementary angle measures 40 degrees.
Step-by-step explanation:
Given that one of the angles of a pairs of complementary angles is 50 degrees, to find the ratio of the pair of complementary angles, the following calculation must be performed, knowing that the sum of two complementary angles is equal to 90 degrees:
X + 50 = 90
X = 90 - 50
X = 40
Therefore, the other complementary angle measures 40 degrees.
