A guide defines a natural sequence as consecutive ranks in one suit. Beside the definition, a picture labels 4♥, 5♥ and 7♥ as valid. Something is missing—but it is worth checking exactly what before changing the rule.
Read the cards literally
Four is followed by five, then seven. Six is absent. All three suits match, so the problem is the rank gap rather than the suit. Moving seven to the other end of the row cannot fill that gap.
There are several possible explanations
The image may have omitted 6♥. A nearby instruction may designate a card as wild. The image might belong to another variant or revision. Each possibility needs evidence from the surrounding material; the green tick itself supplies none of it.
If the exercise has no wild cards and the displayed inventory really contains only those three cards, the group fails the written definition.
Make the smallest correction
Replace 7♥ with 6♥ and the group becomes 4♥, 5♥, 6♥. This repairs the example without changing the definition. Alternatively, adding the missing 6♥ produces a four-card sequence, but only if an additional card is actually available and that group length is permitted.
Those repairs are different: one replaces a card, the other increases the inventory. Neither should be described as sorting. A clear worked example shows the actual correction so readers can reproduce the result with the cards they have.
