Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
Answer:
192
Step-by-step explanation:
The sum of the first 3 terms of the A. P is
a + a + d + a + 2d = 18, that is
3a + 3d = 18 ← substitute a = 4
12 + 3d = 18 ( subtract 12 from both sides )
3d = 6 ( divide both sides by 3 )
d = 2
Thus the first 3 terms are
4, 6, 8 and their product = 4 × 6 × 8 = 192
