Question

105,112,119 find the 29 term​

Answer 1

Step-by-step explanation:

The given series is an arithmetic progression.

"How do I know that?"

I know that because the given terms have a common difference of 7.

Now, we know.... (hopefully)

$an \: = \: a1 + (n - 1)d$

where an = nth term of AP

n = the position of the nth term in an AP

a1 = Initial term of AP.

d = common difference of the AP.

In the question you have asked...

n = 29

a1 = 105

d = 7

a29 is to be found.

so.. according to formula:-

a29 = 105 + (29-1)7

a29 = 105 + 28(7)

a29 = 301

Therefore 301 is the 29th term.

Hoped this helped! Best regards.
