whats the next 3 terms in the number pattern

Question

Find the next three terms in the number pattern. 0, 3,7, 12

a.18,24,32

b.17,23,30

c.18,25,32

d.18,25,33

Answer 1

d 0,3,7,12,18,25,33,42,52...

a1 = 0

a2 = a1+3 = 3

a3 = a2 +4 = 7

a4 = a3 +5 = 12

a6 = a5 +6 = 18

a7 = a6 + 7 = 25

a8 = a7 + 8 = 33

a9 = a8 +9 = 42

a10 = a9+10 = 52

the nth term is

an = an-1 + n
