Lucia knows the fourth term in a sequence is 52 and the ninth term in the same sequence is 82. complete the explanation of how she can find the common difference for the sequence. then use the common difference to find the second term of the sequence

well, I really can't really understand the way you asked the question, But, If it helps I can give you the entire sequence all the way to 82.

The sequence is,

2, 12, 22, 32, 42, 52, 62, 72 , 82, ect...,

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
