Answer:
Step-by-step explanation:
The n-th term is given by ...
an = a1 + d(n -1)
for common difference d and first term a1.
You have a sequence with a first term 4 and a common difference of 6-4=2, so the formula is ...
an = 4 + 2(n -1)
__
Using n=8, we find ...
a8 = 4 + 2(8-1)
a8 = 18
A2 + b2 = c2
Number 1 is 15.1986.... or 15.2
Explanation: 5 squared is 25 and 16 squared is 256. Subtract 256 minus 25 to get 231, then divide it by the square root.
Number 2 is 7.21111.... or 7.2
Explanation: 6 squared plus 4 squared is 52, square root of 52= 7.2
