Question

8/3/9/10/17 ? Find the series

Answer 1

Answer:

25

Step-by-step explanation:

8+3-2=9

3+9-2=10

9+10-2=17

10+17-2=25

Answer 2

Concept:

A recursive function is a function that its value at any point can be calculated from the values of the function at some previous values.

For example, suppose a function f(k) = f(k-1) + f(k-2) which is defined over non negative integer. If we have the value of the function at k =1 and k = 2, we can also find its value at any other non-negative integer

Given:

8/3/9/10/17

Find:

Find the series

SOLUTION:

8+3-2=9

3+9-2=10

9+10-2=17

10+17-2=25

In equation it can written as,xₙ=xₙ₋₁+xₙ₋₂-2

Therefore, the series can be represented as a recursive function, xₙ=xₙ₋₁+xₙ₋₂-2
