Answer:
-30
Step-by-step explanation:
Tn = a1 + (n-1)d = 34 + (-2)(n-1) = 34-2n+2 = 36-2n
hence,
10= 36-2n
2n = 36
n = 13
20 terms from the last term would be 13+20 = 33
T33 = 36-2(33) = -30
Answer:
juliet collected 50 cans
Step-by-step explanation:
let x be rosanas cans
10+x+2x = 130
simplify
10 + 3x = 130
3x = 130 - 10 = 120
x = 120/3 = 40
rosanas cans = 40
juliets cans = 40 +10 = 50
santiagos cans = 50 x 2 = 100
but i think the question is wrong!!
