An+1= 3n+3 +2
An+1 - An = <span>3n+5 -3n-2=3
An is aa arithmetic sequence
its sum is given by:
A0 +A1 +A2 + . . . + An = N(Ao + An) /2
where N = n-0=n
</span><span>S50= A0 +A1 +A2 + . . . + A50 = 50(Ao + A50) /2
</span>
S50 = 50(Ao + A50) /2
Ao=2, A50=150+2=152
S50= <span>50(Ao + A50) /2
</span>
finally
<span>S50=25*154=3850</span>

The correct answer for the question that is being presented above is this one: "xy / pm = 8." The equation that models the situation is this xy <span>/ pm = 8
</span>
<span>If x varies directly with the product of p and m and inversely with y:
</span><span>x = pm/y
</span>2 = 0.5*2 / 4
8 = 1
Then,
xy / pm = 8
Answer:
1) She can buy three packages and have no beads left over
2) $16.5
Step-by-step explanation:
