Answer 1

a P.A (2,4,............44) possui quantos termos?

R = A2 - A1
R = 4 - 2
R = 2


An = A1 + (N - 1)*R
44 = 2 + (N - 1)*2
44 = 2 + 2N - 2
44 = 2N
2N = 44
N = 44/2
N = 22


PA = {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44}


RESPOSTA

$\textbf{\displaystyle\large{A~~PA~~TEM~~22~~TERMOS}}$
