Question

Determine os 8 primeiros termos da sequência (45,15,5)

Answer 1

a1 = 45
a2 = a1q = 15
q = 15/45 = 1/3 ****
a4 = a1q³ = 45* (1/3)³  = 45 * 1/27   = 45/27  = 5/3 
a5 = 45 * (1/3)^4 = 45 * 1/81 = 45/81 = 5/9
a6 = 45 * (1/3)^5 = 45 * 1/243 =45/243 = 5/27
a7 = 45 * (1/3)^6 = 45 * 1/729 = 45/729 =5/81
a8 = 45 8 (1/3)^7= 45 * 1/2187= 45/2187= 5/243
