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
