Answer:
16 is correct
Step-by-step explanation:
6 ,12 ,18, 24, 30 ,36 ,42, 48,
She will keep adding by 6
This is an isosceles triangle, so both legs are of length 5√2.
Use the Pyth. Thm. to find the length of the hypotenuse. Square 5√2 and double the result: 25(2) = 50; twice 50 is 100. The square of the length of the hyp. is 100, and so the length of the hyp is sqrt(100), or 10 (answer).
A
this is an arithmetic sequence whose n th term ( explicit formula) is
= 
+ (n - 1 )d
where d is the common difference and the first term
here d = 10 - 8 = 8 - 6 = 6 - 4 = 2 and = 4, hence
= 4 + 2(n - 1 ) = 4 + 2n - 2 = 2n + 2 → A
