ANSWER
C) 1, 3, 6, 10, 15, 21, 28, 36, 45
EXPLANATION
The recursive formula is,
when n is a natural number greater than 1.
When n=2,
when n=3,
when t=4,
When t=5,
when t=6,.
when t=7
When t=8,
When t=9,
Hence the first nine triangular number are
Answer:
This has one real solution, x=4
Step-by-step explanation:
8 - 4x = 0
Add 4x to each side
8 - 4x+4x = 0+4x
8 =4x
Divide each side by 4
8/4 = 4x/4
2 =x
C and E
13 cups
1.5 pint= 3 cups
8 fluid ounces = 1 cup
4 bottles of milk with 1.5 pint each= 3x 4= 12 cup
8 fluid ounces of strawberry syrup= 1 cup
12+1=13 cups
Both are correct!
if R = 26 - 17 = 9
now the next one
17 + R = 26
Same thing as R = 26 - 17 = 9
The next number is 127
The sequence is the previous number times 2 plus one.
