This is an algorithm for computing the sum of an arithmetic progression with first term $19$

and common difference $7.$

Tell how many elementary operations this algorithm uses.

Your answer depends on $n.$

Step $1$ Set S$=19,$k$=1,$ and t$=19.$

Step $2$ while $\}$k$$

$($a$)$ Replace t with t$+7.$

$($b$)$ Replace $\}$S$\backslash$mathrm$\{$ with $\}$S$+$t$\backslash$mathrm$\{.$

$($c$)$ Replace $\}$k$\backslash$mathrm$\{$ with $\}$k$+1\backslash$mathrm$\{.$

endwhile

Step $3$ Print S$.$
