222-212! Im pretty sure that’s the answer
The explicit formula for a arithmetic sequence is a_n = a_1 + (n - 1)d.
We want to find a_21.
a_21 = 17 + (21 - 1)(10)
a_21 = 17 + (20)(10)
a_21 = 17 + 200
a_21 = 217
The 21st term is 217.
Answer:
Step-by-step explanation: largest=2x+4
their sum =2x+2x+4=36
4x=36-4=32
x=32/4=8
so the numbers are 2*8,2*8+2,2*8+4
that is 16,18,20
