Question

cinco termos em que o 1termo e=x+3 e a razão e x

Answer 1

r = x
a 1 = x + 3
r = a 2 - a 1
a 2 - a 1 = r
a 2 = r  + a 1
a 2 = x + x + 3
a 2 = 2 x + 3
a 3 = a 2 + r
a 3 = 2 x + x = 3 x + 3
a 4 = a 3 + r
a 4 = 3 x + 3 + x = 4 x + 3
a 5 = a 4 + r
a 5 = 4 x + 3 + x = 5 x + 3
P.A.(X + 3  ;  2 X + 3   ;  3 X + 3   ;  4 X + 3   ;  5 X + 3 )
