T_n = 3 * T_(n-1)
Long way (always works!)
T_5 = 3*T_4,
T_4 = 3*T_3
T_3 = 3*T_2
T_2 = 3*T_1
T_5 = 3*3*3*3*T_1 = 81*T_1 = 81*8 = 648!
Short way (sometimes it works!)
T_n = 3^(n-1) * T_1 (this case is a geometric series of ratio-=3)
T_5 = 3^4*8 = 648
Answer:
i think its .625
Step-by-step explanation:
all you need to do to make a fraction into a decimal is divide the nominator by the denominator
Answer:
The answer to your question is cost of 0.6 pound of candy $4.17
