Answer:1) 2n - 1
2) 99
see in the picture, u can see that the number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
......
=> The above sequence has: u1 = 1
d = 2
=> u(n) = 1 + 2(n - 1) = 2n - 1
=> the number of shaded squares in the n figure is 2n - 1
b) the number of shaded squares in the 50th figure is 2.50 - 1 = 99
Step-by-step explanation:
F(1) = 7
f(2) = 7 + 6 = 13
Recursive formula => f(n + 1) = f(n) + 6
Next term = 31 + 6 = 37.
Does not do instrument and sport will be 2 (middle). Then you can go horizontol for does not play sport with the total being 7 (middle right) . 25 - 7 = 18 (top right). 18 - 16 = 2 (top left). 5 + 2 = 7(Bottom left)
Hope it helped because i cant really draw on it. :<
Are there options for me to analyze from?
Answer:
d. -4
Step-by-step explanation:
- 4p – 12 = 8 + 4p + 5p
- 4p – 12 = 8 + 9p
- 4p – 9p = 8 + 12
- – 5p = 20
- p = 20 ÷ (– 5)
- p = – 4
