A partial sum of an arithmetic sequence is given. Find the sum. 14 (3 + 0.26k) k = 0

72.3

Step-by-step explanation:

Given that:

The arithmetic sequence:

The first term of the sequence = 3 since k = 0

i.e (3 + 0.26(0)) = 3

The last term of the sequence = 6.64

i.e (3+ 0.26(14)

= (3 + 3.64)

= 6.64

Total no of terms = 15 i.e from 0 to 14

∴

The partial sum of the arithmetic sequence =

= 72.3

3=log(n)=2

answer a: product property

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
