For this you need to note that "n" represents position of sequence.
y1 is y on position 1 and so on. Sequence goes: y1,y2,y3,y4... and so on
So all you have to do is to implement values 1,2,3,4,5 for n and get 5 members of sequence. (start from 0 if your n starts from 0)
y0 = -5
y1 = -5-5 = -10
y2 = -15
y3 = -20
y4 = -25
y5 = -5*5 - 5 = -30
Answer:
False
True
False
Step-by-step explanation:
X = 180-68 = 112
Z = 180 - 128 = 52
Y = 128 - 68 = 60
Only the second row is equal. The first row can't be equal because it says -2=-1/2
Answer:
12
Step-by-step explanation:
The apple equals 7
the pear equals 13
and the pomegranate equal 6
7+6 = 13
7+7+7 = 21
7+6+13=26
6+6=12
How I came to this conclusion was starting with the problem with one variable.
3 apple =21
so 21/3 = 7
Now this is the tricky part.
7 + x = z but also, 7 + x + z =26
So I plugged 6 into x, and got 13 for z.
7 + 6 = 13, and also 7 + 6 + 13 = 26.
The answer is y is equal to 60°
