Hope this helps ;)

Good luck ^^

Answer 2

Answer:

See below

Step-by-step explanation:

Here we have a function $a$ such that $a: \mathbb{N}\to \mathbb{R}$ and $a:n \mapsto a(n) = a_n$

The sequence is denoted as $\{a_n\}_{n\in\mathbb{N}}$ such that $\mathbb{N} = \{1, 2, 3, ...\}$

For this sequence, we would have

$\left\{ {2^n\right\}_{n = 2}^8$

But sure it seems to follow

$\left\{ {2^n\right\}_{n = 2}^\infty$
