Find the 7th term of the arithmetic progression whose first term is 5 and common difference is 4.

Step-by-step solution

1. Identify the sequence as an arithmetic progression (AP).
2. Use the formula for the nth term of an AP: $t_n=a+(n-1)d$.
3. Substitute $a=5$, $d=4$, $n=7$: $t_7=5+(7-1)\times 4=5+6\times 4=5+24=29$.
4. Thus the 7th term is 29.
