Find the nth term of this quadratic sequence
2, 8, 18, 32, 50, ...

nth term =  2n^2

Step-by-step explanation:

The computation of the nth term of the quadratic sequence is as follows;

The given sequence is 2,8,18,32,50

Now

The first term, n = 1 = 2 × 1 × 1 = 2

Second term, n =2 = 2 × 2 × 2 = 8

Third, n =3  = 2 × 3 × 3 = 18

fourth term, n = 4,  = 2 × 4 × 4 = 32

fifth term, n =5,  = 2 × 5 × 5 = 50

Now finally  For nth term,  =  2  × n × n = 2n^2

Therefore nth term =  2n^2

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
