Answer:
6, 10, 8
Step-by-step explanation:
aₙ= aₙ₋₁ - (aₙ₋₂ - 4)= aₙ₋₁ - aₙ₋₂ + 4
a₅= -2
a₆= 0
-----------
aₙ₋₂= aₙ₋₁ - aₙ + 4
- a₄= a₅- a₆ + 4 = -2 - 0 + 4 = 2
- a₃= a₄ - a₅ + 4 = 2 - (-2) + 4 = 8
- a₂= a₃ - a₄ + 4 = 8 - 2 + 4 = 10
- a₁= a₂ - a₃ + 4 = 10 - 8 + 4 = 6
The first 3 terms: 6, 10 and 8

Answer:
4
Step-by-step explanation:
The sum of n terms of a geometric series with first term a1 and common ratio r is given by ...
Sn = a1·(r^n -1)/(r -1)
for r=5 and n=6, this becomes ...
15624 = a1·(5^6 -1)/(5 -1) = a1·(15624/4)
Then we have ...
1 = a1/4 . . . . . divide by 15624
4 = a1 . . . . . . multiply by 4
The first term of the series is 4.
