What is sequence and example?

A sequence is an ordered list of numbers . The three dots mean to continue forward in the pattern established.
Each number in the sequence is called a term. In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.

sequence

The statement is true for n = 0 because 0 is divisible by 3.
Now suppose we have proved the statement for some n element of N This means that 4^n -1 = 3k for some integer k..
We now consider the quantity 4^n+1 -1 = 4 . 4^n - 1 = 3 . 4^n + 4^n - 1
We use the inductive hypothesis to simplify that equation to 4^n+1 - 1 = 3 . 4^n + 3k = 3 (4^n + k).
We have thus shown that 4^n+ 1- 1 is a multiple of 3.

Answer:

(x + 7)(x + 8)

Step-by-step explanation:

${x}^{2} + 15x + 56 \\ = {x}^{2} + 8x + 7x + 56 \\ = {x}(x + 8) + 7(x + 8) \\ = \huge \red{ \boxed{ (x + 8)(x + 7)}}$
