Question

Is − 451 in the sequence below? 15, 7, −1, −9, −17, ...

Answer 1

Answer:

If - 451 is in the sequence , then the number of terms should be a natural number .

Step-by-step explanation:

first term = 15

difference = -8

term given = -451

BTC

15 + ( n - 1 ) × -8 = -451

15 -8n +8 = -451

23 - 8n = -451

-8n = -451 -23

-8n = - 474

n = 474 / 8

n = 59.25

so -451 is not a term of this sequence since value of n is 59.25 , not a natural number
