Which number is composite in 23897993?
A composite number is a number that has multiple factors (9: 1,3,9)
Answer: X = 30*
All circles = 360*
we can subtract 260 from that because we know the length of one so we know the other is 130.
We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50
Answer:
Step-by-step explanation:
I don’t know why they bother teaching recursive formulas as the explicit is almost always used :)
For 2,9,16,23...
Recursive is a(n+1)=an+7
Explicit is an=2+7(n-1)
(or more neatly an=7n-5)
For 2,14,98,686...
Recursive is a(n+1)=7an
Explicit is an=2(7^(n-1))
(or (2/7)7^n )
