Within the set of whole numbers , one set of numbers satisfies the recursive formula an=(an-1)^2-an-1, when a4=870 what are the first two terms of the sequence?

A

Step-by-step explanation:

3 and 6 will be the first and second term of the given series respectively.

Explanation:  since it is given-   and

so, by replacing n by 4, we will get- ⇒870= ⇒

after solving this equation we will get, and 30.

If , but it is not a whole number.

Thus, will be the value of third term of the given series.

Again, by applying the given condition , or -5 (not possible), so, will be the second term.

Similarly, or -2 but  we will go to the whole number.

Thus, will be the first term.
