Question

Dada a pa ( 28,36,44) determine seu 29 termo

Answer 1

$a_{1} =28$

$r=36-28=8$

$a_{29} =\:?$

$a_{n}=a_{1}+(n-1)\:.\:r$

$a_{29}=a_{1}+(29-1)\:.\:r$

$a_{29}=a_{1}+28\:.\:r$

$a_{29}=28+28\:.\:(8)$

$a_{29}=28+224$

$a_{29}=252$

Answer 2

Dada a pa ( 28,36,44) determine seu 29 termo. r = a2-a1 r = 36-28 r = 8 an = a1 + (n-1).r a29 = a1+(29-1).r a29 =a1+28r a29 = 28+28.8 a29 = 28+ 224 a29 = 252
