Answer 1

Answer:

Answer. => n = 25, Therefore : 124 is the 25thterm of the given sequence, Hope you understand, Have a great day !

Answer 2

Step-by-step explanation:

Now since we have to find the next two term of the series so the 4th term of the series will be

t4=a+(4−1)d−−(i)t4=a+(4−1)d−−(i)

By substituting the values we get

⇒t4=4+3×5 =4+15 =19⇒t4=4+3×5 =4+15 =19

And also the fifth term of the series will be equal to

t5=a+(5−1)d−−(ii)t5=a+(5−1)d−−(ii)

Hence by substituting the values we get

⇒t5=4+4×5 =4+20 =24⇒t5=4+4×5 =4+20 =24

So the fifth term of the series is 24

Hence from the above observations we can say the 4th term of the given AP series is 19 and its 5th term is 24.

So the next two terms of the series is 4, 9, 14, 19, 24

So, the correct answer is “4, 9, 14, 19, 24”.
