Ascending Sequence Problem: Find First Positive in -10,-7, _, _, _

To solve this problem, we'll follow these steps:

• Step 1: Identify the common difference between the given terms.
• Step 2: Extend the sequence using this common difference.
• Step 3: Determine when the first term turns positive and identify its position.

Let's proceed with the solution:

Step 1: The common difference $d$ can be calculated by subtracting the first term from the second term:
$d = -7 - (-10) = 3$.

Step 2: Using this difference, we extend the sequence:
Third element: $-7 + 3 = -4$
Fourth element: $-4 + 3 = -1$
Fifth element: $-1 + 3 = 2$

Step 3: Check when the first positive number occurs:
The sequence becomes positive at the fifth element with the value $2$.

Therefore, the solution to the problem is that the first positive number occurs at the Fifth element.
