Answer:
- 32, - 26, - 20, - 14
Step-by-step explanation:
To find the first 4 terms , substitute n = 1, 2, 3, 4 into the rule
a₁ = 6(1) - 38 = 6 - 38 = - 32
a₂ = 6(2) - 38 = 12 - 38 = - 26
a₃ = 6(3) - 38 = 18 - 38 = - 20
a₄ = 6(4) - 38 = 24 - 38 = - 14
Would it be 2:1? I really don't know, I haven't learned that yet, sorry
So the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64
The answer is C hope this can help
B) c - 1/5c - 40 = 120
c- (original cost) - 1/5c (sale) - 40(coupon)= 120(final cost)
Hope that helps! :)
