The equation for slope is y=mx+b. slope is m. 2 is the slope. so you know the m part of the equation is 2. just by eliminating the answers that don’t have 2 as the slope, A is your answer.

Salutations!
To find the nth term, you will be needing a formula.

a stands for the first term (first number in the sequence)
d stands for the difference between two terms. (always remember to subtract from the 2nd term to the 1st term)
and the n is what we are going to find
so in your sequence: 5, 10, 15, 20
5 is a (as it is the first term)
d would be 5 ( 10 -5 =5)




your nth term is

Hope this helps!
Have a great day!
