Vedclass · Answer

(C) Let us analyze the differences between consecutive terms in the sequence:$25 - 13 = 12$$40 - 25 = 15$$57 - 40 = 17$$79 - 57 = 22$$103 - 79 = 24$$130 - 103 = 27$The pattern of differences is $12, 15, 18, 21, 24, 27$. If we apply this pattern starting from $13$:$13 + 12 = 25$$25 + 15 = 40$$40 + 18 = 58$ (instead of $57$)$58 + 21 = 79$$79 + 24 = 103$$103 + 27 = 130$Since $57$ does not fit the pattern,it is the odd number.

Find the odd number in the given sequence: $13, 25, 40, 57, 79, 103, 130$.
