Question

Find the thirtieth term of the following sequence.

Answer 1

The answer to the question is 52

Answer 2

Answer:

The thirtieth term of sequence is 52

Step-by-step explanation:

Given the A.P series

-6, -4, -2, 0, ...

we have to find the thirtieth term of the following sequence.

The A.P is -6, -4, -2, 0, ...

which implies

Common difference, d=-4-(-6)=-4+6=2

First term=a=-6

n=30

$a_n=a+(n-1)d$

$a_{30}=a+29d$

$a_{30}=-6+29(2)=-6+58=52$

hence, the thirtieth term of sequence is 52
