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
