Question

Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10? ​

Answer 1

10, 8, 6, 4, 2, ...

Answer 2

The sequence generated will be 10,8,6,4,2,......

Explanation:

We want to generate a sequence here

f(n + 1) = f(n) - 2

f(1) = 10

So f(2) = f(1) - 2 = 10 -2 = 8

f(3) = f(2) - 2 = 8-2 = 6

f(4) = f(3) -2 = 6-2 = 4

f(5) = f(4) - 2 = 4-2 = 2

So the sequence will be ;

10, 8 , 6 , 4 , 2 , •••••••••
