Question

Calcule a razão da progressão aritmética (1/4, 1/2, 3/4 ...)

Answer 1

$a_1={1\over4}\\ \\ a_2={1\over2}\\ \\ a_3={3\over4}\\ \\ a_2-a_1=a_3-a_2\\ \\ {1\over2}-{1\over4}={3\over4}-{1\over2}\\ \\ {2-1\over4}={3-2\over4}\\ \\ {1\over4}={1\over4}\\ \\ r={1\over4}~~~~ou~~~0,25$

Answer 2

a1 = 1/4

a2 = 1/2

1/2 - 1/4 = >>>>> mmc = 4

( 2 - 1 )/4 =  1/4 *****razão r **** resposta
