Write a recursive rule for the sequence 4,10,16,22
Phantasy [73]

Answer:

a_{n+1} = a_{n} + 6

Step-by-step explanation:

The terms have a common difference d between consecutive terms, that is

10 - 4 = 16 - 10 = 22 - 16 = 6

To obtain the next term add 6 to the previous term ( recursive rule ), thus

a_{n+1} = a_{n} + 6 with a₁ = 4

Find two consecutive whole numbers such that the sum of their squares is 221.
Law Incorporation [45]
n^2+(n+1)^2=2n^2+2n+1=221
2n^2+2n=220
n^2+n=110
n^2+n-110=0
(n-10)(n+11)=0\implies n=10,n=-11

But since n must be a whole number, we ignore n=-11. So the two integers are n=10 and n+1=11.
