Answer: brad will have $112 in his account after 6 months.
Step-by-step explanation:
Since he puts equal amount of money in his savings account once a month, the rate at which the money is increasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = $27
d = 44 - 27 = 17
n = 6 months
We want to determine the value of the 6th term, T6. Therefore,
T6 = 27 + (6 - 1)17
T6 = 27 + 85
T6 = $112
