Find the 55th term in the following arithmetic sequence

-102, - 98, - 94, - 90

114

Step-by-step explanation:

-102,-98,-94,-90 ...

lets give the numbers a name : T,

and the number order is 1, 2, 3, 4,5 ... n

we can see:

Tn=T (n-1) + 4;

Tn=T (1) + (n-1) 4, T1 = - 102

now n=55

T (55) = - 102 + (55-1).4=114
