=1+(50-1)4
=1+200-4
=201-4
=197 Ans

Thnk u...🙏
1,5,9,13,17...
Ans:-50th term=197
First question: 197
Q3.
Solution:- 10.......99
Starting two digit number divisible by 3 is 12,15,18.......99 ending
a=12
d=3
An=99
n=?
An=a+(n-1)d
99=12+(n-1)3
99=12+ 3n-3
99=9+3n
99-9=3n
90=3n
n=90/3
n=30 ans
Thank you sir
Maths seh mohabbat krnah heh 🥰

sir ans 197
second ka ans= 66
Q4.
Solution:- a=2 , d=2, n = 50
Sn=n/2(2a+(n-1)d
Sn= 50/2 (2x2+ (50-1) 2
=25(4+100-2)
=25x102
=2550 ans
An = 50 , find "n" first
1) 1,5,9,13.............50th
=197
2) 4,8,12,..................264
=1056
3) find all two digit which are divisible by 3.
=33
4) 2+4+6+8..........50th
=2550
Cen I know how it was 2550 I have got 2650
QA. 1,,5,9,13,17. 50th position=?
An= 197
QB. 4,8,12,....264
n=66
QC. All two digits no. Divisible by 3
12, 15, 18,21,....99
n=30
QD. 2+4+6+8+10,...50th
Sn=2500
Q2.
Solution:- a=4
d=4
An=264
N=?
An=a+(n-1)d
264=4+(n-1)4
264=4+4n-4 (plus 4 & minus 4 cancel)
264=4n
264/4=n
So, n=66 ans
boring subject 😂😂 so long 😂😂 not interested 😂😂
