The given sequence is
a₁ = 29
a₂ = 39
a₃ = 49
a₄ = 59
This sequence is an arithmetic sequence. Th first term is a₁ = 29, and the common difference is d= 10.
The n-th term is
The 33-rd termis
a₃₃ = 29 + (33 - 1)*10
= 29 + 320
= 349
Answer: a₃₃ = 349
a₁ = 29

Remember
and
if
where x=x then m=n
so
so
m+n=-6
so test the options
first one works
2nd ones doesn't
3rd one doesn't
4th one doesnt'
answer is first option, m=3 and n=-9
