<h3>How to Solve Arithmetic Progression?</h3>
The formula for the nth term of an arithmetic sequence is;
aₙ = a + (n - 1)d
where;
First term is a
Common difference is d
n is nth term
We are given;
First term; a = 13
Common difference; d = 2
Thus, after the first ten weeks, number of recipes she would have mastered is;
a₁₀ = 13 + (10 - 1)2
a₁₀ = 31

1/3 of the classroom is mopped in five minutes, so the whole classroom (or one classroom) is mopped in 15 minutes
We have: 2/25= 24/?
Cross multiply:
2*?= 25*24
⇒ 2*?= 600
⇒ ?= 600/2
⇒ ?= 300
