Question

Fill in the gaps in this sequence: -8, -19, -30, _ , _.
(Geometric and arithmetic sequences)

Answer 1

-8, -19, -30, -49 , -60

Step-by-step explanation:

Here we have the following sequence :

-8, -19, -30, _ , _

• First term of sequence is -8 .
• Second term of sequence is -19 : $-8-11 = -19$
• Third term of sequence is -30 : $-19-11 = -30$
• Fourth term of sequence is : $-30-11 = -49$
• Fifth term of sequence is : $-49-11 = -60$  

Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. $a = -8$ and common difference $d = -11$ having general equation as : $-8 -11n$ .
