Will the sum of the three even numbers be odd or even?

Anna35 [415]

Answer:

Even.

Step-by-step explanation:

They will be even.

All even numbers, by definition, are divisible by 2.

We can write 3 even numbers as 2m, 2n and 2p.

So the sum = 2m + 2n + 2p

= 2(m + n + p).

This proves it because the sum is a multiple of 2 and must be even.

Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2

Mrrafil [7]

Given:

$a_1=-4$ and $a_n=a_{n-1}+9$ where $n\geq 2$ .

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

$a_n=a_{n-1}+d$

Where, d is the common difference.

We have,

$a_n=a_{n-1}+9$

Here, d=9.

The first term of the AP is $a_1=-4$ .

The explicit formula for an AP is:

$a_n=a_1+(n-1)d$

Substituting $a_1=-4$ and $d=9$ , we get

$a_n=-4+(n-1)9$

$a_n=-4+9n-9$

$a_n=-13+9n$

Therefore, the required explicit formula for the given sequence is $a_n=-13+9n$ .
