Answer:
Please check the explanation below.
Step-by-step explanation:
As we know that quadruple is basically a fourfold amount or number.
For example,
The quadruple of 6 is 24.
4 x 6 = 24
Similarly, the quadruple of 10 is 40.
4 x 10 = 40
Now, let me solve your query.
Given the expression
2 - 2
as
2-2 = 0
so
we have to determine the quadruple of 0.
i.e.
4 x 0 = 0
Therefore, 0 is the quadruple of 2-2 (or 0).
I hope, it has cleared your concept.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the sequence
11, 13, 15, 17, 19, ...
Determining the Recursive formula:
We know that a recursive formula is termed as a formula that specifies each term of the given sequence using the preceding terms.
From the given sequence it is clear that every term can be obtained by adding two to the previous term.
i.e. 13 = 11+2, 15 = 13+2, 17 = 15+2, 19 = 17+2
so
aₙ₊₁ = aₙ+2, for n ≥1
Therefore, a recursive formula is:
Determining the Explicit formula:
Given the sequence
11, 13, 15, 17, 19, ...
An arithmetic sequence has a constant difference 'd' and is defined by

computing the differences of all the adjacent terms

The difference between all the adjacent terms is the same and equal to

also

so substituting
,
in the nth terms



Therefore, the Explicit formula is:

I believe it’s 12000 because 30x50=1500 1500x2=3000 now 3000x4=12000
