(B) Let us analyze the pattern of the series: $1, 2, 5, 11, 10, 17, 28$.If we look at the differences between consecutive terms:$2 - 1 = 1$$5 - 2 = 3$$11 - 5 = 6$$10 - 11 = -1$This does not follow a clear pattern.Let us re-examine the series by splitting it into two alternating series:Series $1$: $1, 5, 10, 28$Series $2$: $2, 11, 17$This also does not seem to follow a simple arithmetic progression.Let us check the pattern of adding consecutive odd numbers:$1 + 1 = 2$$2 + 3 = 5$$5 + 6 = 11$ (Here,if we add $5$ instead of $6$,we get $10$)$11 + 6 = 17$$17 + 9 = 26$Actually,the series follows the pattern of adding consecutive odd numbers starting from $1$ $(+1, +3, +5, +7, +9)$:$1 + 1 = 2$$2 + 3 = 5$$5 + 5 = 10$$10 + 7 = 17$$17 + 9 = 26$Comparing this with the given series $1, 2, 5, 11, 10, 17, 28$,we see that $11$ is incorrect and should be $10$,and $28$ is incorrect and should be $26$. However,looking at the options provided,the term $28$ is clearly the one that breaks the sequence $1, 2, 5, 10, 17, 26$. Thus,$28$ is the wrong term.
