The first three terms are: 25, 125 and 625

Step-by-step explanation:

Given

Required

The first three terms

The nth term of a geometry progression is:

So, we have:

First term:

Second term:

Third term:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
