Answer 2

My first number is -2 my fifth number is 26

My third number is 12

Given :

My first number is -2 my fifth number is 26

Lets assume the given numbers are in arithmetic sequence

First term is -2  and fifth term is 26

$a_1=-2\\a_5=26$

Formula for nth term is

$a_n=a_1+(n-1)d$

where d is the difference and n is the number of terms

$a_5=a_1+(5-1)d\\a_5=-2+4d\\26=-2+4d\\26+2=4d\\28=4d\\divide \; by \;4 \\d=7$

Common difference is 7

First term is -2

second term is $-2+7=5$

Third term is $5+7=12$

So , the third number is 12
