Question

Find the next four terms in the arithmetic sequence.

Answer 1

Answer:

Correct choice is C

Step-by-step explanation:

The first term of arithmetic cequence is -15, the second term is -7, the third term is 1 and i.e.

The difference between two consecutive terms of the arithmetic sequence is the difference of the arithmetic sequence. Thus, the difference of the arithmetic sequence is

$-7-(-15)=-7+15=8\text{ that is exactly } 1-(-7)=1+7=8.$

Hence,

• fourth term is $1+8=9;$
• fifth term is $9+8=17;$
• sixth term is $17+8=25;$
• seventh term is $25+8=33.$

Next four terms are 9, 17, 25, 33.
