find the 1st difference given the second and third term. second term is 3a+5 ; third term is 8a−3 .(1 point)
To find the 1st difference, we need to subtract the second term from the third term.
Let's write out the expressions for the second and third terms:
Second term: 3a + 5
Third term: 8a - 3
Now, subtract the second term from the third term:
(8a - 3) - (3a + 5)
= 8a - 3 - 3a - 5
= (8a - 3a) + (-3 - 5)
= 5a - 8
Therefore, the 1st difference is 5a - 8.
To find the first difference, we need to subtract the second term from the third term.
The second term is 3a+5 and the third term is 8a−3.
Subtracting the second term from the third term, we have:
(8a−3) - (3a+5)
To subtract the terms with a variable (a), we need to combine like terms.
8a - 3a = 5a
And
-3 - 5 = -8
Therefore, the first difference is 5a - 8.
