The seventh number in a sequence of numbers is \(31\) and each number after the first number in the sequence is \(4\) less than the number immediately preceding it. What is the fourth number in the sequence?

A. \(15\)
B. \(19\)
C. \(35\)
D. \(43\)
E. \(51\)


GIVEN: term7 = 31

Each number after the first number in the sequence is 4 LESS than the number immediately PRECEDING it.

This means, term8 = 31 - 4 = 27
And term9 = 27 - 4 = 23
And term10 = 23 - 4 = 19
And so on.

This also tells us that each term is 4 GREATER than the number immediately FOLLOWING it.
So, for example, term6 = 31 + 4 = 35
And term5 = 35 + 4 = 39
And term4 = 39 + 4 = 43

Answer: D
