A series is given with one term wrong. Select the wrong term from the given alternatives. -913, -916, -924, -937, -955, -975, -1006, -1039
-975
In a wrong-term series we first read the pattern of the correct terms and then find the single term that breaks it.
All terms are negative, so ignore the sign and study the magnitudes: 913, 916, 924, 937, 955, 975, 1006, 1039.
Look at the differences between consecutive magnitudes: \(916-913=3\), \(924-916=8\), \(937-924=13\), \(955-937=18\).
These gaps are 3, 8, 13, 18 — an arithmetic pattern that increases by 5 each step, so the next gaps should be 23, 28, 33.
Applying the expected gap of 23 to 955 gives \(955+23=978\), so the sixth magnitude should be 978, i.e. the term should be -978.
The series instead prints -975, which does not fit the required difference of 23.
Continuing correctly, \(978+28=1006\) and \(1006+33=1039\), which confirms the rest of the series is consistent.
Hence the wrong term is -975.

In the following question, four number pairs are given. In each pair the number on left side of (−) is related to the number of the right side of (−) with some Logic/Rule/Relation. Three pairs are similar on the basis of same Logic/Rule/Relation. Select the odd one out from the given alternatives.
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. E.g.13 − Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
