Answer:
Tn = 75+25n
Step-by-step explanation:
The balance are in arithmetic progression
$100, $125, $150...
The formula for calculating the nth term of the sequence is expressed as;
Tn = a+(n-1)d
a =100
d = 125 - 100 = 150 - 125
d = 25
n is the number of terms
Substitute
Tn = 100+(n-1)*25
Tn = 100 + 25n-25
Tn = 75+25n
Hence the nth term of the sequence is Tn = 75+25n

Answer:
$7,596.43
Step-by-step explanation:
The cost of the college tuition is increasing 5% compounded annually for 5 years.
∴ A = P(1 + r%)ⁿ
where A = tuition fee after 5 years.
P = current tuition
r = rate of increase
n = period
A = $5,952(1 + 5%)⁵
= $5,952(1 + 0.05)⁵
= $5,952 × 1.05⁵
= $7,596.43
=
That would be .
Hope this helps.
