Answer:
→402 is not a term in the given sequence.
Step-by-step explanation:
Given sequence is 8,13,18,23,...
First term = 8
Common difference = 13-8= 5
⇛18-13=5
⇛23-18=5
Since the common difference is same throughout the sequence
⇛8,13,18,23,... are in the AP.
Let nth term = 402
We know that
nth term of an AP = an = a+(n-1)d
Now,
an = 402
⇛8+(n-1)(5) = 402
⇛8+5n-5 = 402
⇛5n+3 = 402
⇛5n = 402-3
⇛5n = 399
⇛n = 399/5
n can not be rational number it should be a positive integer.
402 is not a term in the given sequence.
