The first and last one i think
6/6.2 OR 0.627
Step-by-step explanation:
6(1)/6.2 = 6/6.2 OR 0.627
N=1,
a1= 48-1*11=48-11=37
a2= 48 -2*11=48 -22=26
d= 26 -37 = -11
a(n) = a(n-1) - 11
a1=37
a(n) = a(n-1) - 11
Check:
a1=37, a2= a1-11 =37-11=26
a3= 48 -3*11=48-33=15 (using explicit formula),
and a3=a2 - 11=26 -11 =15 (the same answer)
Answer is B.
Here are ways to make 224:
122 x 2
56 x 4
32 x 7
28 x 8
16 x 4
(3x^1/2 y^4/x^2 y^3)^2
=9x y^8/x^4y^6
=9y^2/x^3
Answer is then: =9y^2/x^3
