Find 437 th term of the arithmetic sequence whose first term is
Brrunno [24]

The 437th term of arithmetic sequence is 36.

Step-by-step explanation:

First term = a_{1}= -73

Common difference = d = \frac{1}{4}

Term to find = 437th

Therefore,

n= 437

The formula for arithmetic sequence is;

a_{n}=a_{1}+(n-1)d\\

Putting values;

a_{437}=-73+(437-1)(\frac{1}{4})\\a_{437}=-73+(436)(\frac{1}{4}\\a_{437}=-73+\frac{436}{4}\\a_{437}=-73+109\\a_{437}=36

The 437th term of arithmetic sequence is 36.
