Answer:
First term a = 6
Step-by-step explanation:
a (first term) = ?
r (common ratio) = 3
T₈ (8th term) = 13122
The nth term of a geometric progression gp is
Tn = arⁿ⁻¹
T₈ = ar⁸⁻¹
T₈ = ar⁷
13122 = a * 3⁷
13122 = a * 2187
a = 13122 / 2187
a = 6.
The first term a = 6
infinite many
(5 x (-20)) * (100 x (0.7))
11 packages
24/6=4
44/4=11
subtract 5 from both sides. -1.6r=-5 divide both sides by-1.6. r=-5/-1.6 simp;ify-5/1.6 to 3.125. r =3.125
