Answer:
- 920
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = 22- 30 = 14 - 22 = 6 - 14 = - 8
This indicates the sequence is arithmetic with sum to n terms given by
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 30 and d = - 8 , thus
= [ (2 × 30) + (19 × - 8) ]
= 10(60 - 152)
= 10 × - 92
= - 920

Answer:
r=-39
Step-by-step explanation:
-6(2r + 8)= -10(r-3) solve -6(2r+8)
-12r-48= -10(r-3) solve -10(r-3)
-12r-48= 10r+30
+48 +48
-12r=-10r+78
+10r +10r
-2r=78
-2r/-2=78/-2
r=-39
