Question

Which of the following expression would give a sequence with a first term of -4 and a common difference of 3

Answer 1

Answer:

D) 3n-7

The $n^{th}$ of the given sequence   $t_{n} = 3n -7$

Step-by-step explanation:

Explanation:-

Given that the first term a = -4

Given that the common difference 'd' = 3

The $n^{th}$ of the given sequence

$t_{n} = a+(n-1)d$

$t_{n} = -4+(n-1)3$

$t_{n} = -4 + 3n -3$

The $n^{th}$ of the given sequence   $t_{n} = 3n -7$
