Answer 1

Answer:

8

Step-by-step explanation:

~~The rule here is -- Multiply by 2 and then subtract 3.

~~They have given the second term of the sequence which is 13. So, we have to reverse the rule to get the first number.

**The rule says that first we multiply by 2 and then subtract 3.

1. So, the first operation we apply on 13 is add 3 to it ( as it was the last operation performed to get 13 and we are transposing it from LHS to RHS ).

2. And we get 13+3 = 16.

3. Then we divide the number by 2 ( multiplication of two has been transposed from LHS to RHS and the sign changes ).

4. And we get 16/2 = 8
