<h3><u>Question:</u></h3>
Identify a3 of this sequence: 0.25, 0.5, 0.75, 1, 1.25, 1.5,...a3=
<h3><u>Answer:</u></h3>
The third term of sequence is 0.75

<h3><u>Solution:</u></h3>
Given that, sequence is:
0.25, 0.5, 0.75, 1, 1.25. 1.5
Let us find the difference between terms

This is a arithmetic sequence
Because the difference between any term and its immediately preceding term is always 0.25
In a arithmetic sequence,

Thus, in the sequence 0.25, 0.5, 0.75, 1, 1.25. 1.5

Thus the third term of sequence is 0.75
