The correct syntax for a range in bash is {START..END..INCREMENT}, so $\{1\ldots7\ldots3\}$ is interpreted as {1..7..3}, which generates a sequence starting from 1 to 7 with an increment of 3, resulting in 1, 4, 7.

Consider the Following Script {1…7…3}\{ 1 \ldots 7 \ldots 3 \}{1…7…3}

Consider the Following Script $\{ 1 \ldots 7 \ldots 3 \}$
