Question

Is 0 is a term of the sequence 71,68,65?

Answer 1

$\huge \mid{ \underline{ \overline{ \underline{\overline \pink{\bold{ \: \: Aɴsᴡᴇʀ \: \: } }}} }}\mid$

an = a + ( n - 1 )d

here,

• a = 71
• d = -3
• an = 0

➪ 0 = 71 - 3n + 3

➪ 3n = 74

➪ n = 74/3

➪ n = 236.6

so, 0 is not a term of this sequence.

Answer 2

Answer:

an=a+(n-1)d

here,

a=71

d=-3

an=0

o=71-3n+3

3n=74

n=74/3

n=236.6

So, o is not a term of this sequence
