Step-by-step explanation:

Hey, there !!

It's simple lets get started with simple solution,

Given the sequences are,

10,8,6,4....

Then,

common diifference= 2

now, we have formula,

[tex]an = a1 + d(n - 1)[/tex]

[tex]or \: an= 10 + 2(n - 1)[/tex]

[tex]or \: an \: = 10 + 2n - 2[/tex]

[tex]an \: = 2n + 8[/tex]

[tex]or \: an = 2(n + 4)[/tex]

Therefore, The answer is an = 2( n+4) or, 10+2(n-1)...

{ note: 2(n+4) is simplified form of 10 +2(n-1).}

Hope it helps...
