Answer:
330
Step-by-step explanation:
Evaluate the sum of 14 terms and subtract the sum of the first 3 terms
The sum to n terms of an arithmetic sequence is
= 
[ 2a₁ + (n - 1)d ], so
= 7 [ (2 × 6) + (13 × 3)]
= 7(12 + 39) = 7 × 51 = 357
= 6 + 9 + 12 = 27
Sum of terms from 4 th to 14 th = 357 - 27 = 330
We are to find the dot product of the given vectors. To find this just multiply the coefficients of i terms(horizontal components) and multiply the coefficients of j terms(vertical components), and add the two products together, as shown below:
a.b = (6i + 5j).(-5i+4j)
a.b = 6(-5)+5(4)
a.b = -30 + 20
a.b = -10
The dot product results in a scalar quantity, so you only get a magnitude not a vector.
