Answer:
1. 12th nth Term
2. 56
3. October and P5,500
Step-by-step explanation:
1. -24 yan not 24
formula:
(12-3n) where n is the nth term
12-3n=-24
-3n=-24-12
-3n/-3=-36/-3
n=12
So -24 is 12th term
2. 2+4+6+8+10+12+14 =56
or Sn=n(n+1) -- formula for even number
Sn=7(7+1)
Sn=7(8)
Sn=56
3. He save P1000 in October
formula
(n/2)(firstnumber+last number)
=(10/2)(1,00+1000)
=(5)(1,100)
=P5,500
