Question 18

Geometric Sequence Formulas

Answer 18

1st term: a
2nd term: ar^1
3rd term: ar^2
nth term: a(n)=ar^n-1
Sum of the first n terms: {a [1 - (r^n)]} / (1 - r)
r= common ratio

Question 19

What percent of Y is Z?

Answer 19

What (X) Percent (1/100) of Y is (=) Z?

(X) x (1/100) x Y = Z

Question 20

What percent of 25 is 5?

Answer 20

What (X) Percent (1/100) of 25 is (=) 5?

(X) x (1/100) x 25 = 5 –> (25/100)X = 5 –> X= 20

Question 21

Arithmetic Sequence Formulas

Answer 21

1st term: a + 0d
2nd term: a + 1d
3rd term: a + 2d
nth term: a + (n - 1)d
Sum of the first n terms: (n/2) x [2a + (n - 1)d]
a= first term
d= common difference
