What do these words mean: "the first tow terms"?

Comment from student: The sum of the first two terms of a geometric sequence is 100 times the first term. What is the common ratio?

OK. So, we have

a + a*q = 100*a,

where a is the first term of the geometric progression and q is the common ratio.

Divide both sides of this equation by a. You will get

1 + q = 100.

Hence, q = 100 - 1 = 99.
