Answer:
Let the first number be
2
n
−
1
∴
the second number must be
2
n
+
1
We are told that the product of the numbers is 35
∴
(
2
n
−
1
)
(
2
n
+
1
)
=
35
4
n
2
−
1
=
35
4
n
2
=
36
n
2
=
9
→
n
=
±
3
Then, either, first number
=
(
6
−
1
)
=
+
5
∴
second number
=
5
+
2
=
+
7
or
First number
=
(
−
6
−
1
)
=
−
7
∴
second number =
−
7
+
2
=
−
5
