Sagot :

To find the 1st difference given the second and third terms, we'll follow these steps:

1. Identify the given terms:
- Second term: [tex]\( 3a \)[/tex]
- Third term: [tex]\( 8a - 3 \)[/tex]

2. Subtract the second term from the third term to find the 1st difference.
[tex]\[ \text{1st difference} = \text{third term} - \text{second term} \][/tex]

3. Substituting the given terms into the subtraction:
[tex]\[ \text{1st difference} = (8a - 3) - (3a) \][/tex]

4. Simplify the expression:
[tex]\[ \text{1st difference} = 8a - 3 - 3a \][/tex]

5. Combine like terms:
[tex]\[ \text{1st difference} = 8a - 3a - 3 \][/tex]
[tex]\[ \text{1st difference} = 5a - 3 \][/tex]

Therefore, the 1st difference is [tex]\( 5a - 3 \)[/tex].

[tex]\[ \boxed{5a - 3} \][/tex]
