Step-by-step explanation:
Hope this helped :)
(3,-1) just fill it in and the only one that makes sense is the first one
So the general formula is:
a(n)=1+n^2
Let's check:
a(1)=1+1^2=1+1=2
a(2)=1+2^2=1+4=5
a(3)=1+3^2=1+9=10
a(4)=1+4^2=1+16=17
The next numbers in the sequence should be:
a(5)=1+5^2=1+25=26
a(6)=1+6^2=1+36=37 etc.
208- ( 2* 46)= X
208- 92=2x
x=58
The length is 58cm.
Check by:
58*2 +46*2
116+92= 208
