Age Problem. Please help. I suck at these.
eimsori [14]
Let Cynthia's age be C, then Abigail's age A

since Abigail is 8 years older, her age A = C+8.

20 years ago Cynthia's she was C-20 and Abigail was A-20=3(C-20)

A-20=3C-60
A=3C-40
but we just said A=C+8
so 3C-40=C+8
2C=48
C=24
A=24+8=32

Cynthia's age is 24 and Abigail's age is 32

What is the 50th term of the sequence for -20,-14,-8,-2....
kkurt [141]
-20 to -14 is 6
-14 to -8 is 6
-8 to -2 is 6

aritmetic sequence
an=a1+d(n-1)
a1=first term
d=common difference
n=which term

first term is -20
common difference is 6
we want 50th term

a50=-20+6(50-1)
a50=-20+6(49)
a50=-20+294
a50=274

the 50th term is 274

Gre4nikov [31]

Answer:

d = w + 3 (first equation)

2d = 2w + 3 (second equation).

The second equation is equivalent to the first one.
