$7(3+4i)$ is equivalent to $21+28i$

Option D is correct option

Step-by-step explanation:

We need to find the equivalent to the given expression:

$7(3+4i)$

To solve the expression multiply 7 with the terms inside the bracket

$7(3+4i)\\=7(3)+7(4i)\\=21+28i$

So, $7(3+4i)$ is equivalent to $21+28i$

Option D is correct option

Given the formula for an arithmetic sequence f(7) = f(6) + 4 written using a recursive formula, write the sequence using an arit

natita [175]

Answer:

Of(7) = f(1) + 24

Step-by-step explanation:

Since this Arithmetic Sequence can be written recursively as a function, then we can write the whole sequence, by adding the common difference to the previous function. So writing it as an Arithmetic formula is (placing an example, with a common difference of 4 units):

$\left.\begin{matrix}n &1&2&3&4&5&6 &7\\f(n)&2&6&10 & 14&18&22&26 \end{matrix}\right|\\f(n)=f(n-1)+d\:\: (Recursive \: Formula)\Rightarrow a_{n}=a_{n-1}+4\: \: \: (Arithmetic\: Formula)\\Of(7)=f(1)+6*4\Rightarrow a_{7}=a_{1}+(7-1)4\Rightarrow a_{7}=a_{1}+24\\$
