What is the 100th term of the sequence with a1 = 222 and d = -5? PLEASE HELP VERY URGEN

-273

Step-by-step explanation:

This is an arithmetic progression and the formula to find the nth term is given as:

= a + (n-1)d

Therefore, the 100th term will be:

= a + (n-1)d

= a + (100 - 1)d

= a + 99d

where a = 222

d = -5

Therefore, a + 99d = 222 + 99(-5)

= 222 + (-495)

= 222 - 495

= -273

but which class are u may know that first
