A sequence of numbers follows the rule: multiply the previous number by -2 and add 3. The fourth term in the sequence is -7. Give the next 3 terms in the sequence. Give the 3 terms that came before -7 in the sequence.

Next 3 terms: 17, -31, 65

3 terms before -7: 2, -1, 5

Step-by-step explanation:

Fourth term in the sequence = -7

Rule for finding the next term:

Therefore, the fifth term:

Sixth term:

Seventh term:

Let the three terms that came before -7 be:

As per question statement:

Again applying the given rule:

Again applying the given rule:

Therefore the 3 terms before -7 are:

2, -1, 5
