The simple formula for the nth term of an arithmetic sequence is an = 4n + 16. What is the explicit formula corresponding to the simple formula? A.an = 4 + (n - 1)(16) B.an = 16 + (n - 1)(4) C.an = 16 + 4n D.an = 20 + (n)(4) E.an = 20 + (n - 1)(4)

an = a1 + (n - 1)d

where d = common difference and a1 = first term

so its a???
welshfella
  • welshfella
in your case d = 4

mhm
welshfella
  • welshfella
no
anonymous
  • anonymous
ik its not a and b
welshfella
  • welshfella
the coefficient of n is d in the explicit formula so that makes d = 4 but what value will a1 have?
welshfella
  • welshfella
why do you say its not b?
welshfella
  • welshfella
oh i see - no its not b

i think its c

im i right>??

simplif each of the options and see if you get 4n + 16
welshfella
  • welshfella
no
anonymous
  • anonymous
how when its already 16+4n
welshfella
  • welshfella
20 + (n - 1)4 = 20 + 4n - 4 = ?
anonymous
  • anonymous
the -4 will cancel out
anonymous
  • anonymous
so it will be left with 2o+44n then you divide both by 4
welshfella
  • welshfella
you need the explicit formula where you can easily pick out the first term and the common difference
welshfella
  • welshfella
20 - 4 = 16
anonymous
  • anonymous
so its d
welshfella
  • welshfella
theres only 1 left lol
anonymous
  • anonymous
d
welshfella
  • welshfella
e = 20 + (n - 1)4 = 10 + 4n - 4 = 4n + 16 so its e
anonymous
  • anonymous
ok EXPLAIN PLZ
welshfella
  • welshfella
* that is 20 + 4n - 4 in second line
anonymous
  • anonymous
ik that
welshfella
  • welshfella
- well it simplifies back to 4n + 16 and a1 + (n - 1)d is the explicit formula
anonymous
  • anonymous
oooo lol thx
