Matches were used to make the pattern attached:
Complete the table:
Number of triangles ($t$t) | $1$1 | $2$2 | $3$3 | $5$5 | $10$10 | $20$20 |
---|---|---|---|---|---|---|
Number of matches ($m$m) | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
Write a formula that describes the relationship between the number of matches ($m$m) and the number of triangles ($t$t).
$m$m = $\editable{}$ $t$t
