Answer:

$S_{n}$ = n² + 4n ; n = 11

Step-by-step explanation:

$S_{n}$ = $\frac{n}{2}$ [2 $a_{1}$ + (n - 1)d]

~~~~~~~~~

$a_{1}$ = 5

d = 7 - 5 = 2

$S_{n}$ = $\frac{n}{2}$ [ 2(5) + 2(n - 1)] = $\frac{n}{2}$ ( 8 + 2n ) = 4n + n²

$S_{n}$  = n² + 4n

n² + 4n = 165

n² + 4n - 165 = 0

(n + 15)(n - 11) = 0 ( n ≥ 0 ) ⇒ n = 11

sergiy2304 [10]

You would have to get 56 points everyday.
If you subtract 1300 from 1580 you get 280. divide 280/5 which equals 56.
56*5=280
280+1300=1580.
56 is the amount of points you need
