Question

Which two identify the same sequence

Answer 1

The correct answer is options A and E.

f(x) = 6x + 4

f(1) = 6(1) + 4 = 10

f(2) = 6(2) + 4 = 16

f(3) = 6(3) + 4 = 22

`\begin{gathered} \text{When n=1,} \\ a_1=10 \\ a_(n+1)=a_(1+1)=a_2=a_1+6\text{ = 10+6=16} \\ _{}when\text{ n=2} \\ a_(n+1)=a_(2+1)=a_3=a_2+6=16+6=22 \end{gathered}`

Clearly, options A and E are the same sequences.
