a_3 is 45 and a_10 is 98415
Step-by-step explanation:
Given
a_1 = 5
a_2 = 15
First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.
So,

The explicit formula for geometric sequence is:

Putting the value of r and a_1

Putting n=3 in the explicit formula

Putting n=10 for tenth term

Hence,
a_3 is 45 and a_10 is 98415

Answer:−18x>36
Divide both sides by −18. Since −18 is negative, the inequality direction is changed.
x< −18
36
Divide 36 by −18 to get −2.
x<−2
