Answer:
155
Step-by-step explanation:
this an Nth term question. we first need to find the Nth term formula. 10, 15, 20... it is going up in 5 so 5n is the beginning of the formula. we minus 5 from 10 to find out the number before it so 10-5=5. so the formula of the nth term is 5n + 5. now we need to find the 30th term. N is the number of the term we need to find, so we now know that N in the formula we found is 30.
formula= 5n + 5
N in the formula above is 30
we need to substitute 30 in to the formula.
N becomes 30.
formula: 5 (30) + 5.
5x30 + 5.
5x 30= 150 + 5= 155.
therefore the 30th term is 155.
hope this helps :)
