Answer:
71
Step-by-step explanation:
This is an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here d = 2 - (- 1) = 5 - 2 = 8 - 5 = 3 and a₁ = - 1, so
= - 1 + (24 × 3) = - 1 + 72 = 71

A)Declarative because your telling them your favorite subject :)
we can write "m more than t" like this:
A+b=15----(1)
a*b=54----(2)
(1) a=15-b ----(3)
put(3) in(2)
(15-b)*b=54
15b-b^2=54
b^2-15b+54=0
(b-9)(b-6)=0
so b=9 or b=6
if b=9 then a=15-9=6
if b=6 then a=15-6=9
answer two numbers are 6 and 9
