170 270 370 380. 390 the fastest way is using 100 and tens
Answer:
35
Step-by-step explanation:
Since the sequence is so short, you can simply add the terms. It is convenient to do them pairwise, working inward from the first+last:
(-4+14) +(-1+11) +(2+8) +5
= 10 +10 +10 +5
= 35
__
Or, you can find the average term as the average of the first and last terms:
average term = (-4+14)/2 = 5
Then the sum is the product of this and the number of terms:
sum = (number of terms)×(average term) = 7 × 5 = 35
We need to see the graph in order to solve this problem
