The first three terms of an arithmetic sequence are as follows.
Montano1993 [528]

Answer:

The next two terms and 5 and 8.

Step-by-step explanation:

Find the recursive formula (tₙ = tₙ₋₁ + d) of -4, -1, 2.

Arithmetic sequences have a common difference, "d" , between terms.

To find the common difference, subtract a term value from the term value after it.

-1 - -4 = 3

2 - -1 = 3

The common difference is 3.

To find the next term, add 3 to the previous term.

The recursive formula is tₙ = tₙ₋₁ + 3

tₙ = tₙ₋₁ + 3

t₄ = t₃ + 3

t₄ = 2 + 3

t₄ = 5

tₙ = tₙ₋₁ + 3

t₅ = t₄ + 3

t₅ = 5 + 3

t₅ = 8

Eloise is investing in a retirement account. She plans on adding an additional $50 at the end of every year and the expected rat
Kobotan [32]
The amount of money she have one year after she started the investment = 1000((1 + r/t)^nt - 1) / (r/t); where r = 3% = 0.03, t = 12 and n = 1 year.
Amount = 1000((1 + 0.03/12)^(1 x 12) - 1) / (0.03 / 12) = 1000((1 + 0.0025)^12 - 1) / (0.03 / 12) = 1000((1.0025)^12 - 1) / 0.0025 = 1000(1.0304 - 1) / 0.0025 = 12,166.38
Therefore, the amount she has in her bank account at the end of the year is $12,166.38
