Answer:

n^2 + 2n.

Step-by-step explanation:

n = 1 2 3 4 5

term t = 3 8 15 24 35

Diffs = 5 7 9 11

2 2 2 - so the nth term contains n^2.

n^2 = 1 4 9 16 25

t - n^2 = 2 4 6 8 10

This is an arithmetic sequence with nth term = 2 + (n-1)2 = 2n

So the nth term of the quadratic sequence = n^2 + 2n.

Kaylis [27]

Answer:

To find the answer we only need to know,

Total no.of girls and Total no.of right handed girls.

So,

Total no.of right handed girls = 7/8

Total no.of girls = 8/8 (as given in question)

Total no.of left handed girls is,

(Fraction of total no.of girls) - (Fraction of total no.of left handed girls)

= 8/8 - 7/8
