Example Question #1 : Number Sequences

Give the next number in the sequence:

\(\displaystyle 8, 17, 26, 35, \underline{\; \; \; \; \; }\)

Possible Answers:

\(\displaystyle 42\)

\(\displaystyle 45\)

\(\displaystyle 44\)

\(\displaystyle 43\)

Correct answer:

\(\displaystyle 44\)

Explanation:

To form the sequence, begin with the term 8. Each subsequent term is equal to 9 added to the previous term, as follows:

\(\displaystyle 8+ 9 = \textbf{17}\)

\(\displaystyle 17+ 9 = \textbf{26 }\)

\(\displaystyle 26+ 9 = \textbf{35}\)

\(\displaystyle 35+ 9= \textbf{{\color{Red} 44}}\),

the missing term.
