Question

In an ARITHMETIC sequence, the first term is 49 andthe comn on difference is 6. Find the 28th term.

Answer 1

Take into account the following formula for an arithmetiv sequence:

`a_n=a_1+(n-1)d`

where:

a1: first term = 49

n: number of the term = 28

d: difference = 6

replace the previous values of the parameters into the formula for an:

`a_(48)=49+(28-1)\cdot6=49+162=211`

Hence, the 28th term of the sequence is 211
