Question

-3,-5,-7.. then find the nth term of series

Answer 1

Answer:

Tn = -3 + (n-1) × -2

Tn = -3+ -2n + 2

Tn = -1 - 2n

Step-by-step explanation:

we know that for an arithmetic progression,

Tn = a + (n-1)d

where a = first term, and d = common difference

in this case, a = -3 and d = -2. simply substitute :))
