Answer:
The term of A.P sequence
tₙ = 9 n - 26
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given sequence
- 17 , -8 , 1 .......
first term = -17
Second term = - 8
The difference of first two terms
d = - 8 -(-17) = -8+17 = <em>9</em>
The difference of next two terms
d = 1 - (-8) = 1+8 = 9
∴ The given sequence is in A.P ( Arthimetic progression)
<u><em>Step(ii):-</em></u>
The term of A.P sequence
Given a = - 17 and d = 9
<u><em>Final answer</em></u>:-
The term of A.P sequence
tₙ = 9 n - 26
