The arithmetic sequence : A n = 6 n
A 1 = 6 * 1 = 6
A 2 = 6 * 2 = 12
A 3 = 6 * 3 = 18
A 4 = 6 * 4 = 24
A 5 = 6 * 5 = 30
Answer:
The first five terms in the sequence are: 6, 12, 18, 24 and 30.
Sum means to add, so you are adding a and 46 to get k. k is given as 97 so your equation used to solve for a is a + 46 = 97, choice A from above.
Multiply 5 on both sides, you get
g=10x5
g=50
£6.72 not sure but think that’s right, because you divide by ten for ten percent and multiply it by two (20%) then add it to £5.60
