Question

What should come in place of the question (?) in the following series? 4-27, -58, -89,-120, ?

• A. 151
• B. -131
• C. -151
• D. -141

Answer 1

Answer:

C. -151

Series:
(-27, -58, -89, -120, ?)

Find the difference between consecutive terms:

$-58 - (-27) = -31$

$-89 - (-58) = -31$

$-120 - (-89) = -31$

So the pattern is subtract 31 each time.

Next term:

$-120 - 31 = -151$
