‘Suppose’ and ‘if’ both are used to guess, or think, or imagine something and both means the same thing. So, using them together is superfluous. So, ‘if’will be used. 

Bula Chaudhury, Indian swimmer best known for her long-distance swimming feats.

In 2005 she became the first woman to have swum across sea channels of five continents including the Strait of Gibraltar, the Tyrrhenian Sea, Cook Strait, Toroneos Gulf (Gulf of Kassandra) in Greece, the Catalina Channel off the California coast, and from Three Anchor Bay to Robben Island near Cape Town, South Africa.

Here the given series is 123 112 133 112 143

It follows a pattern that,

123

123 - 11 = 112

112 + 21 = 133

133 - 31 = 102 (not 122)

102 + 41 = 143

Hence, the odd man in the given number sequence is 122 instead of 102.
