Step-by-step explanation:
To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term rule
= (3 × 1) + 2 = 3 + 2 = 5
= (3 × 2) + 2 = 6 + 2 = 8
= (3 × 3) + 2 = 9 + 2 = 11
------------------------------------------------------------------
substitute n = 10 into the n th term rule
= (3 × 10) + 2 = 30 + 2 = 32
Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
Answer:
-24+12(d-3)+22=-24+34(d-3)
10(d-3)
10d=-30
d=-30/10
d=3
