Answer:
-8
Step-by-step explanation:
Let the sequence be X.
Xn=a+(n-1)*d
where, n: nth term
a: first term
d: common difference
Given, X2=1
Then, 1=a+(2-1)*-3
or,a=1+3=4
So,X5=4+(5-1)*-3
or,X5=4+(4*(-3))
or,X5=4-12=-8
Answer:
- 8
Step-by-step explanation:
The terms in an arithmetic sequence ar
a, a + d, a + 2d, ...... , a + (n - 1)d
Each term in the sequence is obtained by adding the common difference (d) to the previous term, that is
a₂ = 1
a₃ = a₂ + d = 1 - 3 = - 2
a₄ = a₃ + d = - 2 - 3 = - 5
a₅ = a₄ + d = - 5 - 3 = - 8
