a. -1
b. 0
c. 1
d. 2​

Answer 1

Answer:

a.-1

Step-by-step explanation:

63=(8^2)-1

37=(6^2)+1

15=(4^2)-1

5=(2^2)+1

0=(0^2)-1

so the answer should b -1

Answer 2

Answer:

[a]. -1

Step-by-step explanation:

Sequential and series are basic ideas in arithmetic. A series is an organized collection of components where repeats of any kind are allowed, as opposed to a series, which is the sum of all components. One of the typical examples of a series or a sequence is a mathematical progression.

A list of elements or objects that have been organized in a sequential manner is, in essence, a sequence. A sequence can be defined very simply as the sum of all the elements in it. All of the elements in the series must, however, clearly relate to one another.

An arithmetic series is one in which each term is produced by either increasing or decreasing the previous number by a specific amount.

$63=(8^{2} )-1$

    $=64-1$

    $=63$

$37=(6^{2} )+1$

    $=36+1$

    $=37$

$15=(4^{2} )-1$

   $=16-1$

   $=15$

$5=(2^{2} )+1$

  $=4+1$

  $=5$

$0=(0^{2} )-1$

Therefore, the answer is $-1$
