<h2>Answer:</h2>
11 and 15
<h2>Explanations:</h2>
Given the arithmetic sequence -1, 3, 7 __, __, you are to find the next two terms of the sequence.
The nth term of an arithmetic sequence is given as;

where:
• a is the ,first term
,
• n is the ,number of terms
,
• d is the ,common difference
From the given sequence;
a = -1
d = 3 - (-1) = 7 - 3 = 4
For the fourth term, n = 4;

For the fifth term, n = 5;

Therefore the next two terms of the arithmetic sequence are 11 and 15.
