Answer:
(b) a[1] = -7, a[n] = a[n-1] + 3
Step-by-step explanation:
Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...
an = a1 +d(n -1)
we see that the first term (a1) is -7, and the common difference (d) is +3.
The recursive version of the sequence definition is ...
a[1] = a1
a[n] = a[n-1] +d
So, the appropriate choice is ...
a[1] = -7, a[n] = a[n-1] +3
Answer:
m/_2 = 127°
m/_4 = 127°
m/_1 = 53°
m/_3 = 53°
Step-by-step explanation:
angle 2 and 4 are the same in the diagram.
to get angle 1 and 3 i did:
127°×2°=254°
360°-254°=106°
106°÷2°=53°
If I am correct I do think the answer is 0.10 in decimal, in percentage it is 10% and fraction is 1 out of 30 I am not 100% sure so it would be better to double check
The answer is x = 2 because 8(2) is 16 and 16 - 6 = 10
