Question

A Look for the rules and continue these growing patterns:
(a) 51, 56, 61, 66, _____, _____ .......
(b) 7, _____, 21, 28, 35, _____, _____ ......
(c) 2, 4, 8, 16, 32, _____, _____, _____
(d) 12A, 13B, 14C, _____, _____.

Answer 1

(a)
51 + 5 = 56
56 + 5 = 61
So, we keep adding 5 in the next number to complete the pattern further.
51, 56, 61, 66, 71, 76, 77 .......

(b)
7 $\times$ 1 = 7
7 $\times$ 2 = 14
7 $\times$ 3 = 21
So, we keep writing table of 7 to complete the pattern further.
7, 14, 21, 28, 35,42, 49, ......

(c)
2 $\times$ 1 = 2
2 $\times$ 2 = 4
2 $\times$ 4 = 8
2 $\times$ 8 = 16
So, we keep multiplying 2 with the previous answer received to complete the pattern further.
2, 4, 8, 16, 32, 64, 128, 256

(d)
Here each number increases by 1 and alphabets are written in their order along with the increasing numbers.
12A, 13B, 14C, 15D, 16E.
