10,9,8,7......

Answer 1

Answer: -19

Step-by-step explanation:

Seriously... anyway u already know 4 out of the 30 terms of the sequence. U just count back 26 more numbers. I’ll elaborate further 4 u. Keep in mind u already counted 10,9,8 and 7

6,5,4,3,2,1,0,-1,-2,-3,-4,-5,-6,-7,-8,-9,-10,-11,-12,-13,-14,-15,-16,-17,-18,-19

Since u already counted 10,9,8 and 7 you realize that the 30th number is -19.

No need to thank me. Anything 4 my friends ;)

Answer 2

Answer:

30th term of the sequence is -19

Step-by-step explanation:

first term = 10

common difference = 9- 10 = -1

so, nth term = a + (n-1) d

( where n is number of term, a = first term ,

d = common difference. )

• 30th term = 10 + (30-1) × -1
• 30th term = 10 - 29
• 30th term = -19

i hope it helped...
