Question

write the arithmetic sequence with first term 8 and common difference 3.Is 100 a term of this sequence sequence?​

Answer 1

Step-by-step explanation:

Step-by-step explanation:

Thus, first three terms of the sequence are 10, 13 and 16. Let 100 be the nth term of the sequence. n=31, which is a whole number. Therefore, 100 is the 31st term of the sequence.

Answer 2

Answer:

NO

Step-by-step explanation:

a = 8

d = 3

$T_{n} = a + (n-1) . d$

100 = 8 + (n - 1).3

92 = (n - 1).3

$\frac{92}{3} = n-1$

∴ $n = \frac{95}{3}$

Since 'n' is not a whole number in this case,

∴ 100 is not a term of this sequence
