Answer:
12,24,36,48,60,72,84,96,108,120,132,144,156,168,180,192,204,216,228,240,252,264
Step-by-step explanation:
i don't understand
7-4x= 31
Bring over 7 to the other side
Positive 7 changes into negative 7
7-7-4x= 31-7
-4x= 24
Divide by -4 for -4x and 24
-4x/-4= 24/-4
x= -6
Check answer by using substitution method
7-4(-6)= 31
7+24= 31
31= 31
Answer : C. x= -6
- 12, - 7, - 2, 3, 8
The general terms of an arithmetic sequence are
a, a + d, a + 2d + ....... + a + (n - 1 )d
To obtain consecutive terms in the sequence add d = 5 to the previous term
= - 12
= - 12 + 5 = - 7
= - 7 + 5 = - 2
= - 2 + 5 = 3
= 3 + 5 = 8
