Answer:
8,14,22
Step-by-step explanation:
Tn = n^2 +3n +4
n=1
= 1^2 +3(1) +4
= 1 +3+4
= 8
n=2
= 2^2 +3(2) +4
= 4 +6+4
= 14
n=3
= 3^2 +3(3) +4
= 9 +9+4
= 22
1 - 8
2 - 14
3 - 22
3
3 is a prime number so other than 3x1 3 does not have any other factors
154
.4 x 112 = 280
.95 x 266 = 280
.55 x 280 = 154
y= -8 or 8
Step-by-step explanation
30-6= 24
24/3=8
y=8
15+y=7
y=-8
