Answer:
5a-3b+12c
Step-by-step explanation:
(2a - 3b + 5c) - (-3a - 7c)
Distribute the minus sign
2a -3b +5c +3a +7c
Combine like terms
5a-3b+12c
49 = -7 (t + 1)
49 = -7t + 7
-7 -7
42 = -7t
÷ -7 ÷ -7
-6 = t
t = -7
This is an arithmetic sequence (graph is a line), so function:
a(n) = First term + (n-1) * Common Difference
Here First term = 42 and Common difference = 34 - 36 = -2 so

Answer B.
