Question

Güi) Which term of the sequence -7,-2,3,8.... is 88 ?
(iv) Which term of the sequence 4,9,14,19,.... is 104 ?​

Answer 1

Answer:

20th term

20th term

Step-by-step explanation:

Given sequence -7, -2, 3, 8...

First term, a = -7

Common Difference, d = 5

Say nth term is 88

i.e,

a + (n-1)*d = 88

-7 + (n-1)*5 = 88

(n-1)*5 = 88 + 7 = 95

n-1 = 95/5 = 19

n = 19 + 1 = 20

Hence 88 is 20th term of the sequence.
