Answer:
aₙ= 47 -3n
Step-by-step explanation:
44, 41, 38, 35, 32
This is AP with 1st term of 44 and common difference of -3
nth term of this AP:
- aₙ= a₁+(n-1)d= 44+(n-1)*(-3)= 44 - 3n+3= 47-3n
Answer:
32
Step-by-step explanation:
Side AD = 4
9-5=4
Side DC = 13
a^2+b^2=c^2
5^2+12^2=c^2
25+144=c^2
169=c^2
13=c
Side AC = 15
a^2+b^2=c^2
9^2+12^2=c^2
81+144=c^2
225=c^2
15=c
