A series is given with one term missing. Select the correct alternative from the given ones that will complete the series. −69, −142, ?, −580, −1164, −2332, −4668, −9340
A.−285
B.−290
C.−291
D.−288✓ Correct
Explanation
Each term is multiplied by 2 and then 4 is added (×2+4 pattern); −142×2+4 = −280... checking: −69×2+4=−134; pattern is ×2−4: −69×2−4=−142, −142×2−4=−288. So the missing term is −288.
