Identify az of this sequence: 0.25, 0.5, 0.75, 1, 1.25. 1.5

Identify a3 of this sequence: 0.25, 0.5, 0.75, 1, 1.25, 1.5,...a3=

The third term of sequence is 0.75

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
