Answer:
a_n = 50 - 5n, for n = 1,2, 3, ...
Step-by-step explanation:
a_1 = 50
a_2 = 50 - 5 = 45
a_3 = 50 - 2 * 5 = 40
a_n = 50 - (n - 1) * 5
a_n = 50 - 5n + 5
a_n = 50 - 5n

Hello from MrBillDoesMath!
Answer:
38,39
Discussion:
Call the first integer "n". Then
n + ( n+1) = 77 =>
2n + 1 = 77 => subtract 1 from both sides
2n = 77 - 1 = 76 => divide both sides by 2
n = 76/2 = 38
The first integer is n = 38 and the next consecutive one (= n+1) is 38 + 1 = 39. Finally, 38 + 39 = 77
Thank you,
MrB
