Question

please help me out, i’ve asked earlier but no one helped

Answer 1

Answer: 147

Step-by-step explanation: you just have to replace n in the equation to 30 giving you:

-3+50(30)

Now solve

-3+150=147

Answer 2

Answer:

$\rm T_{30}= 147$

Step-by-step explanation:

Given :-

• The nth term of a sequence is -3+5n .

And we need to find out the 30th term of the sequence . For that simply substitute n = 30 in the given expression to find out the 30th term .

The nth term :-

$\rm\implies n = 30$

The sequence :-

$\rm\implies T_n = 5n - 3$

On substituting :-

$\rm\implies T_{30}= 5*30-3 \\\\\implies\rm T_{30}= 150 - 3 \\\\\implies\boxed{\rm T_{30}= 147 }$

Hence the 30 th term is 147 .
