Question

Multiply the previous term by 3 and subtract 4 The second term of the sequence is 5. Find the difference between the first and fourth terms of the sequence.

​

Answer 1

72

Explanation:

Given that the second term of the sequence is 5, and that we are to multiply the previous term by 3 and subtract 4, we can use that as a recursive formula to find the other terms of the sequence.

The first term of the sequence is:

5*3-4 = 11

The third term of the sequence is:

53-4=11

113-4=29

The fourth term of the sequence is:

53-4=11

113-4=29

29*3-4=83

The difference between the first and fourth terms of the sequence is:

83-11 = 72

So the difference between the first and fourth terms of the sequence is 72.
