<h3>
Numerical sequences</h3>
To find the missing numbers in the sequence, we must identify the rule by which they change.
The <u>sequence starts at 8 and then decreases by 1,</u> therefore, the second term is 7. The third term increases by 4 units with respect to the second, going from 7 to 11, and the fourth decreases again by 1, now remaining at 10.
The fifth term increases again by 4 units, from 10 to 14. This already gives us a clear idea of the rule that the sequence follows.
<h3>Decrease 1, increase 4, decrease 1, increase 4,…</h3>
₊₄ ₊₄
<h2> 8 , 7, 11, 10, 14,...,</h2>
⁻¹ ⁻¹ ⁻¹
<em>In this way, the sixth </em><em>element must decrease by 1</em><em>, that is 13 and the seventh must increase </em><em>by 4, that is 17</em><em>.</em>
8, 7, 11, 10, 14, 13, 17,…
The next numbers that the numerical sequence are 13 and 17, to complete. ✅
