Question

PLEASE HELP ASAP

Write the explicit formula for the sequence {-15,-7,1,9, 17,...}. [ Hint: s = a + (n-1)d ]

Answer 1

hey mate

here is your answer...

given series:

-15,-7,1,9,17,...

here the difference between any two consecutive terms is 8.

so ,the common difference (d)=8

first term(a)=-15

so, the generalised formula will be :

a+(n-1)d

=>-15+(n-1)8

=>-15+8n-8

=>-23+8n

=>8n-23 (Answer)
